Description
Jacdac (https://aka.ms/jacdac) is a protocol designed for easier physical connectivity. Jacdac devices communicate using packets over a bus, where each device can advertise itself and the set of services it provides. A service provides registers, events and commands to communicate with other devices. Jacdac relies on a 3-wire bus for power delivery and data transfer. A purpose-built connector is used to interface with the Jacdac PCB edge connector. Jacdac services are specified to abstract the hardware device from the software implementation. Jacdac integrates into Node-RED by exposing nodes to listen for sensor data, events or send commands.
