If you want to load new software onto a Sonoff, you can use jumper wires to link a USB-to-Serial adapter to the programming header of the Sonoff. However, it’s easy to make a mistake, and loose jumper wires can be really annoying.
This cool little programming adapter simply plugs into a common FTDI-type header, and then plugs into your Sonoff.
No more jumper wires. No more looking up the pinout every time you have to connect them!
This little adapter is going to be featured in the next episode of SuperHouse, which will show how to put any Sonoff model (even new ones that haven’t been released yet) into programming mode.
