This PCB is designed to allow connecting an ESP8266 to the other hardware necessary to run the BrewPi firmware and control fermentation temperatures for your brewery. This specific board was designed to use a LoLin D1 Mini ESP8266 microcontroller and integrate with a 2-channel relay board. It does NOT support an LCD screen. This PCB supports the use of dupont connectors for connecting the relay which allows for a much more compact design than if screw terminals were used.
This board does not have terminals for directly connecting temperature sensors - it is intended to have an RJ-45 jack soldered on, and then be connected to a separate RJ-45 sensor board via an ethernet cable.License: CC-BY 4.0
