Front render of the STM32 vehicle status display PCB

This two-layer PCB was designed as a complementary diagnostic device for an unmanned vehicle. It receives vehicle information over CAN and makes sensor and battery status available through a local touchscreen interface.

Core components

  • STM32G431KBT6
  • Adafruit 2.8” and 3.2” Color TFT Touchscreen
  • ECS-160-12-33-AGN-TR - > 16 MHz Crystal
  • R-78E3.3-1.0 -> Regulator
  • TCAN330G -> 3.3V CAN Transceiver

Interface decisions

The display can be connected through either I²C or SPI. The microcontroller receives vehicle information from another device over CAN, separating the local diagnostic interface from the rest of the platform.
