### New Board Layout
Around 11.2018 Itead changed the layout of the Sonoff Basic ([Discussion #4515](https://github.com/arendst/Sonoff-Tasmota/issues/4515)).
The new board is labeled with "Sonoff RF R2 POWER V1.0"
Around November 2018, Itead changed the layout of the Sonoff Basic ([Discussion #4515](https://github.com/arendst/Sonoff-Tasmota/issues/4515)). The new board is labeled with "Sonoff RF R2 POWER V1.0".
Its an ESP 8285 now with 1MB Flash.
The new version of the Sonoff Basic use an ESP8285 with the 1MB flash integrated into the same SoC chip.
GPIO14 is not inuse anymore. Instead you can use GPIO2 labled as `IO2` on the board.
Unfortunately the GPIO Point is not prepared for a Pin, you will need to solder your cable directly on the Board.
Be carefull, to high or long temperatures can damage the spot and its connectivity.
You should also make sure, that there is no traction on the cable. Fix the cable with a cable tie.
GPIO14 is no longer broken out to a contact on the PCB. Instead you can use GPIO2 labeled as `IO2` on the board. However, you must take care that GPIO2 is in the proper state during the normal power up of the device for the ESP to boot properly.
Unfortunately the GPIO2 PCB contact is not prepared for a pin. You will need to solder your cable directly on the board. Be careful. Too high a temperature or long heating can damage the contact and its connectivity. You should also make sure that there is no tension on the cable. Affix the cable with a cable tie and perhaps some hot glue.
* GPIO0 = KEY
* GPIO0 = BUTTON
* GPIO2 = IO2 (no pullup)
* GPIO12 = RELAIS
* GPIO12 = RELAY
* GPIO13 = LED1
The GPIO2 as User configurable input is implemented in the Sonoff Basic Device Template from V.6.3.0.15 (http://thehackbox.org/tasmota/sonoff.bin)

As alternative to gpio14 you can remove the bi colour led and use gpio13 as input

You can removed the thick wires to use the screw connection for low voltage.
And add a screw terminal next to the relay. This make all high voltage on 1 side of the board
You can remove the thick wires from the PCB to use the screw connection on the output side for low voltage. Then add a screw terminal next to the relay for the LINE OUT. This keeps all high voltage on one side of the board
