# Bus Splitter
The `bus_splitter` directory contains a KiCAD project to attempt reverse engineering the protocol
'monkey-in-the-middle' style. It contains two CAN bus transceivers, with the UART in between them
being passed to a set of header pins. The idea being the RX/TX pins can be attached to an
external microcontroller, allowing message to be inspected, modified and/or passed through as is.
