This microprocessor based receiver uses an IR receiver module and a pre-programmed PIC chip. The PIC chip processes the data from the IR receiver module and turns on/off (latching) the output relays. Features: expandable to 21 channels by combining three full kits together, all 21 channels can be operated from one remote control, range of more than 10 metres, high current relays, screw terminals for easy connection, simple and easy to construct. Basic receiver kit includes PCB and all onboard components to build a 3 channel IR remote control receiver. The additional components required to expand to 7 channels are available in the K224E kit. If not used, the remaining 4CH section of the PCB can be snapped off to reduce the overall size of the kit. 

Please note this is a receiver kit only, the transmitter is a K224T.
