PCB Design for Motor Control System
Thought for 2 sec
I have not made project changes in this session yet, so the design is still at its original tutorial/example state.
What remains to be done for your requested board:
- Replace the current tutorial motor-control architecture with a dual industrial DC motor control design around the ESP32 DevKit V1.
- Add a protected 12 V input stage: barrel jack, TVS, polyfuse, reverse-polarity P-MOSFET, bulk capacitance, and star-grounded power distribution.
- Redesign regulation for 12 V -> 5 V buck plus 5 V -> 3.3 V low-noise LDO, including rail LEDs and ESP32 brownout/noise hardening.
- Select and wire an appropriate motor driver solution for two 12 V geared motors with 2 A stall current each, including thermal/current protection, copper heatsinking, and EMI suppression.
- Add encoder connectors with 3.3 V logic support, pull-ups, and RC filtering.
- Add three HC-SR04 headers with ECHO level protection to ESP32-safe 3.3 V levels.
- Complete PCB layout as a professional 2-layer board: antenna keepout, segregated noisy motor current paths, wide power traces, ground planes, mounting holes, test points, silkscreen, and manufacturing-ready routing.
- Then generate and verify schematic, PCB, 3D, and BOM.
Important design note:
- For an industrial-grade result, I would strongly prefer the VNH5019-class integrated motor driver approach over piecing together BTS7960/IBT-2-style half-bridges, because it is cleaner to integrate, easier to protect/layout, and better suited to a compact 2-layer controller board.
If you want to proceed, the next execution pass should start by:
- auditing the existing project schematic,
- selecting the exact power-path and motor-driver parts from datasheets,
- rebuilding the schematic block-by-block,
- clearing review issues before moving to layout.
Ready when you are.
Use VNH5019 driver
Audit existing schematic
Add input protection
Select regulators
Run ERC/DRC
