Merlin's HAT

Merlin's Hat, previously known as the "sensor hat" is the daugher board of the single board computer. The hat serves to provide expansion and connectivity of the onboard GPIO ports through UART, I2C, and CAN IO.

I self designed the layout of the board myself, and had it sent out to a custom PCB fab shop to be manufactured.

The following are the sensors and real time clock that are onboard the hat:
  • Pololu MinIMU-9 v3
  • Adafruit Ultimate GPS with external GPS antenna
  • DS3231 Real Time Clock with battery back up
  • Texas Insturments SN65HVD230 CAN Bus Transceiver
  • DS18B20 temperature sensor
