README
PocketBeagleCommandStation/README.mdPocketBeagleCommandStation
Through hole version of the PocketBeagle LCC/DCC Command Station. This is a DCC command station that is a LCC node. It implements the OpenLCB train protocol node over LCC and converts that to DCC commands. It includes a booster and puts the DCC signal on the LCC bus (pins 4 and 5). It implements a programming track and implements Railcom. The Command Station uses a PocketBeagle as the processing element and uses the PRUs (Programmable Realtime Units) to generate the DCC signal. (See PocketBeagleCommandStation_SMD for a SMD version.)
