+## Brilliant Smart 20676/05 Series II Smart Wi-Fi Plug with USB
+
+Sold by Mitre 10 this is a AU/NZ standard socket.
+It appears some may have esp8266 (perhaps prior to series II) but this one has the
+[CB2S module](https://docs.libretiny.eu/boards/cb2s/) with the Beken BK7231N.
+
+I'm not sure if this device supports cloudcutter - I just flashed it via UART.
+It might support it if not upgraded.
+
+This unit has a bi-colour red and blue LED. Only the blue is programmable,
+the red is connected in hardware to the relay status.

+
+### Disassembly
+
+This unit is easy to disassemble. There are two screws hidden under small caps on the rear.
+After unscrewing those,
+using a guitar pick around the little gap to loosen the clips and the unit will come apart.
+There are two more smaller screws holding the PCB to the remaining half of the case.
+
+You can flash directly to the outlet with a USB to serial adapter.
+You'll probably need to solder wires to the module but it can remain connected to the PCB.
+You can power the board with 5V (where it's marked on the PCB or at the end of the diode markked D5)
+if you want to use the relay.
+In that case leave the 3.3V disconnected but make sure your UART RX and TX lines are still 3.3V.
