Controlling 4 devices using an RF remote is very easy with this project. This is an Arduino compatible project. NRF24L01 module, Atmega328 microcontroller, 3.3V regulator, and few other components are part of the project. Onboard power LED and an additional functional LED is provided. The project provides 4x TTL outputs that can be interfaced with a relay board, solid-state relay boards, motor drivers, and other projects. The circuit works with 5V DC and requires a few milliamps current. D2 Power LED, D1 optional function LED.
Compatible 4 Channel RF Transmitter
This receiver board is compatible with the 4 Channel RF Remote Transmitter using nRF24L01- Arduino Compatible previously published on our website.
Please refer to the example application diagram below to interface the receiver board with Low Profile 2 Channel Solid State Relay for AC Loads which helps you to drive 2x high voltage loads with 230V AC input. You can use 2x boards for 4 channels control.

Can you use the same schemetic but insted of using the nrf24l01 you use the nrf24l01 + with the extended antenna and using the same components and board ?
sir where is the Recever Code
Uploaded above, thanks
