Based on RX-4MHCS-4B of Aurel, an hybrid module containing a superheterodyne receiver 433.92 MHz full dI HCS decoding, the RF Shield allows you to create an 8-channel receiver based on Arduino, extendable to 12 and controllable via special remote control signed TX-12CH. The sketch loaded Arduino allows you to read, process the incoming data and use it to create the commands I²C-bus with which manages the shield relay FT1079K-7100 (not included). The shield has a buzzer, a trimmer (powered by the same 5 volts that feed the hybrid), of which Arduino reads the cursor via the analog line A2 (in order to set the delay time in delayed release in the monostable mode) and an LED (LD1) which is powered from the line of Arduino D2 when it receives a code recognized as valid, a dip switch 2-pole with which you set the mode of the receiver (or bistable astable). The module RX-4MHCS-4B uses power from the 5V Arduino and is surrounded by the button P1 and the LED LD2; the contacts of the antenna end on a terminal strip miniature that allows to connect the receiving antenna, whether it be a stylus 17 cm long (in this case connects to only one terminal ANT) or an external antenna (in which case the terminal block connects shielded cable, with the screen at GND and the hot pole to ANT). N.B. The Arduino Uno and Arduino Shield I / O expanders are not included.

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