This version of the device supports the new Itead DIY architecture which allows OTA firmware upload (support for OTA upgrade to Tasmota to be confirmed). The Sonoff Basic R3 uses the ESP8255 chip. With this version, the mains power reverts to solder rails directly on the PCB. It also moves the Wi-Fi module to a separate PCB mounted on the main PCB. It makes access to the serial pins quite difficult.
