AI assistance is enabled for this report. Each section marked "AI-Assisted" contains AI-generated engineering observations produced during schematic-phase design review. Findings are based solely on connectivity, component values, and net annotations present in the schematic data at the time of analysis. The AI has no access to PCB layout, routing, thermal data, BOM pricing or availability, assembly constraints, or any information outside the schematic. Findings are observations to investigate, not pass/fail judgments. The absence of a finding for a given device or net does not constitute a clearance. STANDARD MODE — this analysis was produced by the standard model tier.
Based on user-selected TP insertion settings, 8 test point(s) were added and a modified design is available for download. Review the modified schematic and resubmit to update this report.

1.1 Design Overview

AI-Assisted — Orthrus-TX is a single-sheet, flat design built around one STMicroelectronics STM32H745ZIT6 microcontroller. It provides a USB Type-C port, a microSD card socket, two eight-way radio-module sockets, and a set of locking wire-to-board connectors for operator controls and peripherals.

Processing Subsystem

The STM32H745ZIT6 is a dual-core device in an LQFP-144 package. It pairs a Cortex-M7 core running at up to 480 MHz with a Cortex-M4 core running at up to 240 MHz. It carries 2 Mbyte of flash and 1 Mbyte of RAM, the RAM made up of 192 Kbytes TCM, 864 Kbytes user SRAM and 4 Kbytes backup SRAM. Its 16-bit ADCs sample at up to 3.6 MSPS (STMicroelectronics datasheet, pages 1 and 2).

The device includes an on-chip core LDO and an SMPS step-down converter. Its VDD application supply range is 1.62 V to 3.6 V.

Clocking

XTAL1 is a Seiko Epson TSX-3225 fundamental-mode crystal at 24.0000 MHz. It has a ±10 × 10^-6 frequency tolerance at +25 °C and a maximum motional resistance of 40 Ω in its frequency band (Seiko Epson datasheet, source: Tomachie). This frequency sits within the 4 MHz to 48 MHz external oscillator range of the microcontroller. The internal HSI, HSI48, CSI and LSI oscillators remain available alongside it.

Interfaces

J1 is a 16-position USB Type-C receptacle carrying VBUS, CC1/CC2, SBU and the USB 2.0 data pairs for both plug orientations. This gives two differential pairs on the board.

SD_CARD_1 is a Molex microSD socket with card-detect switch contacts. ELRS_1 and ELRS_2 are eight-position Molex 5034800800 module sockets.

The remaining interfaces use Molex 532610xxx-series wire-to-board headers, with between two and eight positions depending on the function. These are BUTTONS_1, BUZZER_1, ENCODER_1, ENCODER_2, JOYSTICK_1, JOYSTICK_2, SWITCHES_1, POT_ANALOG_1, POT_DIGITAL_1, SCREEN_1, PROGRAMMING_1 and POWER_1.

The board carries three status indicators. Seven DOWOSEMI SRV05-4 four-channel, low-capacitance protection arrays (U2 to U8) are fitted on the external I/O (DOWOSEMI datasheet, source: Tomachie).

Power Architecture

The board has three named rails: VCC, GND and Net-(D1-A). Net-(D1-A) is the anode node of the SOD-123 Schottky diode D1.

Regulation is provided by three Diodes Incorporated AP2112K-3.3 fixed 3.3 V linear regulators (LD1, LD2 and LD3) in SOT-23-5 packages. Each regulator is rated for 600 mA output, has a 250 mV typical dropout at 600 mA, includes an active-high enable and output auto-discharge, and provides 65 dB PSRR at 1 kHz. Each also has thermal shutdown at +160 °C (Diodes Incorporated datasheet, page 8).

Temperature Ratings

The AP2112K-3.3 regulators and the TSX-3225 crystal are rated for −40 °C to +85 °C. The SRV05-4 arrays are rated for −40 °C to +125 °C. The documented component ratings therefore support a −40 °C to +85 °C board operating range.

1.3 Footprint Compliance

Production pick-n-place, AOI, AXI, ATE and Design Quality tools rely on proper descriptions of component footprints.

Footprint NamingStatus
7 SMT footprints do not follow IPC-7351B naming
1 footprints (connectors, specialty) — compliance unknown
9 footprints could not be classified for inspection

2 Component Value Properties

Component values should be in the VALUE property, either as a direct value (e.g. 100nF) or as a formula reference (e.g. =Capacitance). The typed property (Resistance, Capacitance, Inductance, Impedance, etc.) holds the actual electrical value; VALUE should point to it or contain the same data.

The part-number cross-check could not be performed: no part-number property is populated on the passive components. The AI-enriched run resolves part identities and enables this check.

2.1 Part Number vs Stated Values

Each passive states its electrical facts twice: in the properties the designer set, and encoded inside the MANUFACTURER part number. This check decodes the manufacturer part number and compares the two. A distributor catalogue number is a different thing and cannot be used here - an LCSC C-number or a Digi-Key -ND number identifies a stock item, it encodes no capacitance, voltage or tolerance, so there is nothing in it to check against. Where the two readings disagree both are shown and neither is assumed correct: if VALUE is wrong the analysis used the wrong number, and if the part number is wrong the BOM orders the wrong part. Only the designer knows which field is authoritative. Parts whose numbering scheme is not recognized are reported as not checked rather than passed.

112 of 112 fitted resistor/inductor/capacitor part(s) carry no ordering part number: C1, C2, C3, C4, C5, C6, C7, C8, C9, C10, C11, C12, C13, C14, C15, C16, C17, C18, C19, C20 (+92 more). Without a part number the BOM cannot state what to buy, and none of the part-number cross-checks in this section can run for these parts. Add a manufacturer part number to each part in the library.

2.2 Capacitor Derating Check

Derating profileBenign (controlled office)
Maximum ambient40 °C
Checks performed0
A capacitor is checked here when the comparison can be made without an operating-point calculation: it has two terminals, sits between a power rail and ground so the rail's resolved voltage is the voltage across it, and states a voltage rating - a Voltage property, or a rating decoded from the part number. Every other derating check - for capacitors and for every other part class - is applied by the AI analysis within its report sections.
6 part(s) sit across a resolved power rail with no stated voltage rating and could not be checked: C1, C17, C29, C38, C39, C54. Record each rating in a Voltage property.

3.4 Diode Polarity / Orientation

Diode polarity and orientation are read from the schematic. IPC-7351B (surface mount) / IPC-7251 (through-hole) Zero Component Orientation (ZCO) requires that pin 1, the cathode, is on the left with the footprint at zero rotation. Tomachie will call out schematic-symbol problems that do not meet ZCO because the PCB layout may have an error, assembly may insert the part backwards, or a novice may wrongly indict a correct part — keeping consistent is the least-expensive path for everyone who handles the PCB.

Capacitors and resistors (datasheets and parameter curves)Datasheets for capacitors and resistors, and the parameter curves they carry (ripple current, derating against temperature, DC bias, a jumper's temperature rise), are obtained on the premium tier only. This standard-tier run reads a datasheet already on file and otherwise states no rating for these parts. The exception is a capacitor on a regulator's input or output rail: this tier obtains its datasheet and curves as well.

4.1 Power Rail Analysis

Net-(D1-A): 5 V assumed by USB convention, because a USB connector power pin is on this net. A design that negotiates a higher USB Power Delivery voltage must state the rail's actual nominal, minimum and maximum voltage — preferably recorded in the design itself, otherwise entered when prompted before the AI review starts. Until it is stated, the assumed 5 V is taken as the intended level.

4.1.1 Rail Voltage Annotation

1 power input(s) into this board were identified - the supplies it takes in at a connector, a terminal or a module socket. Every part on and downstream of each one is judged against what it carries, so the analysis needs its full characterization: whether it is AC or DC, its nominal voltage, the band it operates over, and any level outside normal operation the design must survive.
The preferred way to state a rail's voltage is to record it in the design itself, where it travels with the schematic, survives every re-run, and can be read by anyone who opens the design: add VOLTAGE_NOM, VOLTAGE_MIN and VOLTAGE_MAX properties to the rail's net class directive, and VOLTAGE_EXCURSION_MAX for a survivable level outside normal operation.
Where the design does not state the voltage, you will be prompted to enter each rail's nominal, minimum and maximum operating voltage - and, where one exists, the survivable excursion level - before the AI review starts.
RailRequired information
Net-(D1-A)USB-C default values will be 5.00 V nominal, 4.75 V minimum, 5.50 V maximum.

9 High-Speed Serial Interfaces (HSSI)

2 differential pair(s)

Differential pairs detected from _P/_N naming convention which KiCad uses for differential pair identification. Designer should consider explicit assignment to distinct net classes for each SERDES type to explicitly document layout intent.
1 USB differential pair(s) have no controlled-impedance net class assigned. Assign a 90 Ohm differential net class so the impedance intent carries into PCB layout and length tuning.

9.1 Differential Pairs

Differential pairs with designer-specified class annotations.

None of the 1 differential pairs specify a target impedance (the Impedance column is blank). Strongly suggested: put the value in the class name - e.g. 100_OHM, 90_OHM, 50_OHM. The pairs are already identified by their nets, so the ohm value is the useful part to capture for layout.

11.1 Reset-Time Strap Configuration

Each device below takes part of its start-up configuration from resistors the board fits on pins it samples at reset. Every setting is resolved against that device's own datasheet tables - the combination this board selects, and whether the datasheet marks that combination reserved or invalid.

13.1 Connector Shell Grounding

RefDesTypeIssueRecommendationSeverity
J1HRO-TYPE-C-31-M-13xJ1 (HRO-TYPE-C-31-M-13x): Shell pins share the logic GND net, so the shield-bond strategy is not captured as design intent.USB Type-C R2.5 §3.2.1 requires the receptacle shell to be connected to the PCB ground plane; a shield net bonded to logic GND through R||C satisfies it and does not leave the shell floating. Assign a dedicated schematic net per connector (e.g. SHIELD_GND_TYPE_C, SHIELD_GND_SD) so the pour and bond parts are explicit. A copper pour under the connector and stitched directly to logic GND is an acceptable simplification for a board that has no access to an earth ground and will not be ESD-tested. For professional designs, with or without earth ground access, use a 1 MΩ || 4.7 nF (≥2 kV) from the shield net to logic GND. IEC 61000-4-2.

14.7 PCOLA/SOQ Fault Coverage

PCOLA/SOQ scores how well the configured test methods cover each component and each connection. PCOLA evaluates five device-level properties: Presence, Correctness, Orientation, Live (functional), and Alignment. SOQ evaluates three connection-level properties: Shorts detection, Opens detection, and solder joint Quality. Scores are on a 0–100,000 scale where 100,000 means every property is fully covered. The Combined score is the average of PCOLA and SOQ.

14.7.1 Coverage by Test Method

P=Presence C=Correctness O=Orientation L=Live A=Alignment | S=Shorts O(pins)=Opens Q=Quality

PCOLA/SOQ coverage scores by test method. Scores: 0 (None), 0.5 (Partial), 1.0 (Full).

15.1 Library Symbol Grades

Grading schematic library symbol quality based on pin electrical type definitions:

Grade Definitions
GradeRatingDescription
AExcellentHas Power pins AND properly typed I/O pins (>=90% typed)
BGood>=70% typed OR (>=50% typed AND has Power)
CFairMix of typed and Passive pins (>=40% typed)
DPoorMostly Passive with few typed pins (>=10% typed)
FFailAll pins Passive/Unknown (<10% typed, no ERC)

15.2 Component Library Validation

The shared part-number check could not be performed: no part-number property is populated on the passive components. The AI-enriched run resolves part identities and enables this check.

Checking for generic/incomplete library symbols using statistical patterns.

Library Symbol Issues (1 symbols)
Library NameIndustry NamePart NumberRefDesPinsDistributionIssues
SRV05-4SRV05-4-U2, U3, U4, U5, U6, U7, U86P:6 All pins marked as Passive - likely generic library symbol; No Power pins - may use separate power symbol; Only 1 pin type used - no electrical differentiation

15.2.1 Validation Heuristics

All pins same type: Generic library with no electrical rules

High % passive pins on IC: Incomplete type information

No power pins: May indicate separate power symbol

Low type diversity: Very underspecified library symbol

Power-named pins not typed as Power: Library pin types incomplete

15.3 Symbol vs Datasheet Pin Table

Each symbol's pin numbers are compared with the pin table of its cached datasheet model. A datasheet pin the symbol lacks is a warning only when the datasheet calls it electrical; a pin the datasheet marks NC or mechanical, or a symbol pin the table does not list, is shown for information. An exposed pad is never counted as a mismatch, whether the symbol names it or numbers it one past the last pin. Where it was numbered, the row suggests giving it a name, because a bare number does not tell a reader what the pin is.

5 parts compared with a datasheet model: 5 agree, 0 differ. 15 parts have no cached datasheet model yet; 7 have a cached file that is not this symbol's model and were not compared.
Every symbol with a cached datasheet model matches its pin table.

15.4 Shielded Connector Symbol Quality

Shielded connectors with missing pin names0
All shielded connectors have proper pin names for EMC analysis.
