RF relay control circuit PIC16F628 microcontroller used in the donor card 433MHz RF transceiver module with 8 buttons (433.92 MHz) command is sent to the recipient. Sadder still used in the RF receiver in the receiver module and PIC16F628 has 8 relays.
The transmitter circuit in the receiver circuit relay 12v to 5v supply necessary for working with the required 5v 12v relay spot available in petite pic and relay supply in this way is equal.
RF transceiver circuits of asm, hex, schema, and pcb have all files
Even the poor quality rf modules on the market in the open 50 … 60 m considering that in many areas, making it ideal for remote device control is a useful circuit also remote control nice to have
