From the project
Power and I2C daisy chained over ethernet patch cables.
Pico(Daisy)Chain is a simple standard for creating daisy chains of connected devices, allowing I2C and power to be easily distributed out using ethernet patch cables.
This is a repository containing documentation and reference hardware + software implementations.
All hardware reference implementations are in KiCAD 8+ format with the PCB layout and Gerbers.
- PicoChainReference; A generic reference design breaking out the power and I2C to pin headers, this can be easily adapted to what ever purpose is desired. - PicoChainZero; A reference design using the Raspberry Pi Zero as a I2C…
