The RC Light Systems USB Dongle provides a simple way to update your RCLightSystems products.
This dongle is a standard half duplex serial USB converter.
Note that it is possible to use other dongles to do this (we have tested the JETI USBa - that works fine), or you can built one yourself (put a 10K resister between the RX and 5v pins, and a 1N914 diode from RX to TX on an ebay CP210x based USB serial dongle and run a male servo cable to 5v, Gnd and RX connections).
