## Serial Connection
Sonoff Dual R2 is the replacement for Sonoff Dual. Compared to the Dual the main differences/improvements for the Dual R2 are:
* As the second microcontroller has been removed both relays are now controlled directly by an ESP8285
* The button is now directly connected to the ESP8285
* The header connector is now supported in Tasmota either as individual Switch for a relay or as any sensor

### Solving intermittent relay switch errors
Where most Sonoff's use GPIO to control one or more relays the Sonoff Dual and 4 Channel Inching Relay Assy do use the standard SERIAL interface to control the relays.
