Command Stations and Boosters
This is a collection of LCC/DCC Command Stations and Boosters. The Command Stations are Beagle Board based, leveraging the PRUs in the TI AM335x processors to generate the DCC signals accuratly without worrying about Linux kernel premption or needing a real-time kernel module. The compainion booster is ESP32 based.
