Please see the [Hardware Preparation](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation) page for general instructions.
As always, you need to access the serial interface. The **four serial pins** (3V3, Rx, Tx, GND) can be seen in the picture.

Programming the Sonoff DIY 4CH is a breeze although the on-board-button is not connected to GPIO0. As with all ESP8266/ESP8285 modules pulling GPIO0 to GND is needed to put the chip in programming mode. You need to **connect GPIO0 and GND** during power up.

Luckily both GND and GPIO0 (as KEY 1) are available on the header. A simple jumper between GND and KEY 1 while programming will do.
