Self-learning UHF receiver consisting of a radio receiver board with Motorola decoding and a module equipped with 8 relays (optional) operating in impulse or bistable mode that can switch, in impulsive (500ms timeout) or bistable mode.

Based on a Motorola coding MC14502x standard, it allows a maximum of 19,683 combinations for each channel. It's possible to use multi-channel TX or single-channel TX.

The microcontroller can store individually each channel as we can combine a single-channel TX or a channel of a multi-channel version to each output relay.

Warning! The 8-relay board is not included (see related products). A 17cm length of wire is supplied as an antenna.

This project comes in kit. Some components have to be soldered to the included PCB.​
