*Last 5 boards in stock. They are on a white PCB, not red as pictured.*
This is version 2.0 of the interface board specifically made for CraftBeerPi. Same as the original board it simplifies connecting multiple DS18B20 temperature sensors and solid state relays (SSR) to the Raspberry Pi with screw terminals. It also has a couple of mechanical relays, which are ideal for fermenting by switching power to your fridge or heat pad.
Specifications:
- Power Input: 12VDC - 5A recommended
- Built in 12VDC to 5VDC (3A) power converter
- For Raspberry Pi and DS18B20 temperature sensors
- We set the 5VDC prior to shipping
- 6x SSR 12VDC outputs
- 2x Mechanical relays (250VAC/10A - 30VDC/10A)
- 3x DS18B20 temperature sensor inputs
- 2x Max31865 inputs for PT100 sensors
- 1x Flow meter or Humidity sensor input
- 1x Buzzer
- Additional breakout for such things as LCD or additional flow sensors, level sensors etc

The 12VDC supply to the SSRs ensures reliable switching, If switching directly from the Raspberry Pi, the GPIO pins output 3.3VDC. While this is sufficient for the solid state relays we sell, we can not garauntee this will be the case for other types.
