Use this adapter to install new firmware onto Sonoff devices from ITEAD.
The adapter provides a common 6-pin serial header on one side for connection of a USB-to-serial converter, and a 4-pin header on the other side in the correct format to match the programming header inside many Sonoff models.
Includes controller of the power line, so the Sonoff can be power-cycled without disconnecting.
Note: Does not convert voltage, so you must use a 3.3V USB-to-Serial converter.
The current version comes with both plug and socket header types, but they’re loose so you have to select which one you want and solder it on yourself. The current version also has a button to power-cycle the Sonoff, instead of a jumper. The button is more convenient to use than the jumper on older versions.
Details of the new version:
- 6-pin header matching FTDI cable pinout (with either a socket or a pin header)
- 4-pin header matching many Sonoff models
- Button to allow power-cycling without disconnecting
Compatible Sonoff models include:
- Sonoff Basic
- Sonoff TH10 / TH16
- Sonoff POW
- Sonoff 4Ch Pro
- Sonoff 4Ch Pro R2
