Race timers output to LED display boards using serial data, or by ethernet UDP using a similar serial data stream. One protocol is the Alge display protocol. This fork is intended to support modifying an off-the-shelf LED display board to be driven by a Raspberry Pi (here, the Pi 3B+) to handle the protocol and display information output from the off-the-shelf racing timer via a USB-to-Ethernet adapter and connected to the Pi.
