ESP32 AgBot PCB Design
Worked for 3 mins 5 sec
Blocked: routing could not run because the account is out of execution credits.
Completed so far:
- Renamed the project to ESP32 AgBot Controller and updated the description.
- Added and wired the ESP32 AgBot schematic:
- U1 ESP32 DevKit-style 38-pin module
- Battery VIN/GND input
- L298N 1x6 header with 10k pull-downs on all six control lines
- HC-SR04 header with 1k/2k ECHO divider into IO34
- Servo header with 10k PWM pull-down
- 1x5 sensor bus on 3V3/GND plus three GPIO data lines
- GPS header on ESP32 UART pins IO16/IO17
- Unified GND net
- Removed unrelated legacy 555-timer parts that were present in the project.
- Set PCB size to 100 mm x 80 mm, 2-layer stackup.
- Set routing widths:
- VIN/5V: 1.5 mm
- 3V3: 0.5 mm
- Logic/data: 0.3 mm
- Placed all AgBot components on the PCB.
- Added top silkscreen labels for the ESP32, battery input, motor header, ultrasonic header, servo header, sensor bus, and GPS header.
- Pre-route board check passed after cleanup.
Remaining:
- Run PCB auto-routing.
- Run final ERC/DRC review.
- Fix any routing or review issues.
- Confirm final routed layout status.
One note: the requested 3.0 mm 12V motor power trace rule was not applied because the requested L298N header is signal-only and no 12V motor-power net/header was specified in the schematic.
