teal is a custom board for an home automation system.
It is based on the stm32l462re microcontroller.
The current design replaces caniot-device
boards (i.e. V1 and Tiny boards) based on an 8-bit AVR microcontroller.
Features:
- CAN
- USB
- TCN75A temperature sensor
- UART/SPI/I2C/1-Wire/ADC
- USB or 12V power supply
- Zephyr board definition: teal
- Devicetree: teal_caniot.dts
- Board configuration: teal_caniot_defconfig
