See [here](https://github.com/arendst/Sonoff-Tasmota/issues/3347#issuecomment-413579744) for more background information. - -## Serial Connection - -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. First pop up the top part of the bulb with controlled force. The PCB as shown in the image will become visible. - - -Sonoff B1 PCB - -Sonoff B1 PCB - -The **four serial pins** (3V3, Rx, Tx, GND) as well as the GPIO0 signal line are available as test points and clearly marked. Solder wires to those or use pogo pins as you prefer. - -As with all modules pulling GPIO0 to GND is needed to put the chip in programming mode. You need to **connect GPIO0 and GND** during power up. An additional GND pad is available in the middle of the PCB. - -Hint: The **B1 R2** needs the GPIO0 to be connected to the GND pad in the middle of the PCB. Otherwise the flashing is not working. - -### LED HEX10 Color Codes -The Sonoff B1 uses a TEN charter HEX code for all colors. -Colors tested with firmware 5.9.1 20171107: -* 00000000A0 = WARM -* 000000A000 = COOL -* 0000A00000 = BLUE -* FF14500000 = PURPLE -* 551A8B0000 = DARK PURPLE -* A300000000 = RED -* 00ff000000 = GREEN - - +[PAGE MOVED!](sonoff-b1) \ No newline at end of file
