- CAN transceiver: MAX3051EKA+T
- 5 to 16V power supply with 3.3V LDO: SPX3819M5-L-3-3/TR
- Temperature and Humidity sensing with SHT35-DIS-B or SHT31
- 4 analog inputs, SPI, 2 I2C and UART
- Boot0 pin available for flashing via UART
- Pcb size 47.7mm x 23.2mm
- backside solder pads for differential pressure package
