Our Airwire receiver is based on the Arduino Pro Mini 16Mhz and uses all open source software. This is an easy to assemble kit and gives you access (in the software) to the DCC signal so that you can manipulate it if you wish. The Promini board can also be programmed to be a Transmitter. You can use any DCC output (say from your Digitraxx or other DCC controller) to transmit out over the Airwire Frequencies (channel is adjustable in the software) This does require a small opto isolated input-board (details asap)
We also offer a modification of aftermarket QSI receivers that will work with our DCC amplifier.

Buillding the DCC Amplifier
All receivers need a Booster to turn the logic level DCC output of the receiver board into a full voltage DCC signal that can drive DCC decoders.
