I selected the AO4407C (30V, 14A P-channel MOSFET) for robust reverse-polarity protection, TI’s CSD17575Q3T (30V, 5.5 mΩ) for H-bridge outputs, and SS54B Schottky diodes for flyback protection. These parts meet the current and voltage requirements of the dual 24 V motor driver.

Properties

RF Antenna - Manufacture Options
Add RF matching (L/C), antenna keepout, u.FL or test pad for production verification.
Thermal Management
Add copper pours and vias for MOSFETs/power diodes; define via type and fill as needed. Place thermal relief as per power dissipation calculations.
Test Point Strategy
Dedicated, accessible test points for SWD, all power rails, both current sense, and RF, with accessibility post-assembly/pre-potting.
BOM - Generic Passives Replacement
Action Required: Replace all generic resistors/capacitors/inductors with real MPNs, LCSC part codes preferred, for PnP and BOM completeness.
Input Protection Placement
TVS and reverse-protection must be immediately adjacent to 24V input connector; verify surge creepage/clearance and physical pad size.
BOM - Sourcing
All parts must have distributor MPN, prefer LCSC, flag extended/non-stock for review.
PCB Stackup
2-layer, JLCPCB, copper weight 2 oz (unless alternate specified).
Footprint Assignment - Critical Parts
Action Required: Assign exact, manufacturer-verified footprints for U8 (nRF52840 AQFN), ANT1 (chip antenna), power MOSFETs, SS54 diodes, LM2596 regulators, TE 282837-2 connectors, and TVS D1.
Netlist - GND Net Unification
Action Required: Two GND nets, must unify to single GND net in schematic and PCB.
Manufacturability Checklist - ERC/DRC Status
Pending: Errors must be run and resolved, especially footprints, airwires, and GND duplication.
System Architecture
graph TD PI[Power Input] BC[Buck Converters] MCU[MCU + RF] MD[Motor Drivers] CS[Current-Sense] IO[I/O] DBG[Debug] PI --> BC BC --> MCU MCU --> MD MD --> CS MCU --> IO MCU --> DBG
Connector Mechanical/DFM
Verify all connector footprints, reinforce high-current pads (motor terminals), confirm through-hole and pad sizing for wire gauge.
Potting/IP67 Support
Confirm all major ICs/connectors/supports are potting compatible; plan programming/test before/after potting step.
DFM/Production Notes
Provide fiducial count, paste mask for large pads, soldermask guidance, Pick&Place orientation, and JLCPCB panelization instructions.
Final Manufacturability Review
Upon above completion, rerun ERC/DRC and DFM review until all critical items are clear.
Layout - High Current Trace Rules
Set trace width and clearance for motor outputs and 24V bus. Add to PCB layout rules per calculated current (estimate >15A).
