As identified in this forum post ( https://community.openmqttgateway.com/t/rtl-433-esp32-bme280-but-what-ra dio/1563) , the default builds have incorrect connections for the RTL_433 module. This fixes the default build configuration and crispness the documentation. Co-authored-by: Northern Man <sgracey@Heisenberg.local>

Connect the Emitter and Receiver to a 5V (**3.3V** for CC1101) supply source, 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 `build_flags`.

More information about the [CC1101 wiring](https://github.com/LSatan/SmartRC-CC1101-Driver-Lib#wiring). ( 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. )

## 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.

|
## 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](https://github.com/xoseperez/espurna/wiki/Hardware-Itead-Sonoff-RF-Bridge---Direct-Hack) 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
|
|
[Connect GPIO4 of the ESP8255 to the pin D0 of SYN470](https://1technophile.blogspot.com/2019/08/new-sonoff-rfr3-as-433tomqtt-gateway.html)

|
|
## WIFI RF GATEWAY Hardware setup
|
|
This board doesn't require any hardware modifications.
