Connect the Emitter and Receiver to a 5V or 3.3V supply source, check datasheet of your modules to confirm (3.3V for CC1101), and the ground of your supply source to the ground of your board.

To use the CC1101 module,
ZradioCC1101 must be uncomment in the
User_config.h or added to the
More information about the CC1101 wiring (opens new window). ( Please note that with OMG we are recommending CC1101 GDO2 to be connected to ESP32 D27 and GDO0 to be connected to D12, this is different than the LSatan diagram. This is due to the ESP32 using D2 as part of the boot process. )
# Arduino Hardware setup
# ESP8266 Hardware setup
If the gateway works only when serial monitor is connected don't use D3 use D2 instead (gpio 4) and modify config_RF.h accordingly.
With SRX882 some users reported that D3 is not working use D1 instead in this case and modify config_RF.h accordingly.
# ESP32 Hardware setup
# Heltec SX127X 433Mhz boards
Those boards don't require any hardware modifications.
# SONOFF RF Bridge Hardware setup
Per default there is no need on modifying the RF Bridge hardware, unless you don't want to use the provided RF controller (EFM8BB1). Indeed if you want to extend the protocols supported by the bridge you can bypass this controller (opens new window) and use the ESP8255 capacities to decode RF Signal. The RF processing can be achieved after the modification by either RF, RF2 or Pilight gateways.
# SONOFF RFR3 Hardware setup
# WIFI RF GATEWAY Hardware setup
This board doesn't require any hardware modifications.
