Description

The following issues were observed with mote-hardware v0.0.0. They should be addressed before releasing mote-hardware v0.0.1

Functional

  • RP radio module 2 was DNP due to the 2 week order time for stocking the part. Add the LCSC part number and mark the part for placement.
  • Several components need placement offsets for JLCPCB manufacturing. This can be implemented as a column in the BOM
  • The 3 pin JST SWD connector used the LCSC PN for a horizontal connector rather than a vertical connection
  • 2 pin serial connector should be a 3 pin - missing ground
  • Motor driver footprint and schematic symbol don't match - pin 17 on the schematic symbol are the heatsink pads. Should be connected to ground, but the pin is not exposed on the schematic symbol
  • +3v3 status LED is not connected to the +3v3 net Image
  • Status LEDs are too bright, also should be blue not white
  • GPIO 29 is not connected to the wifi driver :( module. It should be named GPIO29_ADC3 rather than GPIO29 Image
  • Back mounting holes need to be moved inwards to avoid interfering with the motors
  • IMU SD0/SA0 is connected to +3V3 which sets the device ID to 0x6AB Our breakout board uses 0x6A by connecting SA0 to GND
  • Add TVS diodes to all exposed pins (USB, uart, swd, buttons)
  • Missing cutout for LiDAR connector to reach bottom of board

Bonus

  • Aesthetic silk screen and project information
  • Schematic PDFs are not included in the release artifacts
