@RasPiTV@Raspberry_Pi@kicad_pcb I have developed it to connect it to the Raspberry GPIO
1. One part is for a level shifter from 3.3V <-> 5V for I2C/ SPI/RX-TX and other GPIO ports.
2. Two Thermocouple amplifier.
3. Digital I/O which output goes to max 50V 500mA. (for Relays)
4. Lots of connectors..etc..
