Haven buttons1
About the Haven buttons1 PCB
Haven buttons1 is an open source PCB design by FlamingLotusGirls, published on GitHub under the MIT license. It is a 2-layer board measuring 56 × 92 mm, with 50 components from 21 distinct parts.
Other key parts include the PCA9555PW and TLV1117-50IDCYR. By type, the board carries 21 resistors, 8 transistors, 8 switches, 7 connectors, 3 ICs and 3 capacitors.
From the project
Code to support the Haven project
The addition here is an auxiliary board directly connected to our flame control board, intercepting physical button presses and turning them into sequences. This allows us to have more local control of the flame effects without having to rendevous through the RPI. (Control is limited to the valves on that particular box. There's still no way for the boxes to talk to each other.)
