Sonoff Basic flashing jig

thingiverse

I purchased five Sonoff Basics units, anticipating they would feature holes in the pin locations for easy connection. However, it appears Sonoff has altered their products, replacing traditional holes with solder pads instead. In an attempt to modify one of them, I found myself struggling to remove the solder and thought to myself, "This is not going to be a straightforward process." But then, I had an epiphany - my 3D printer and some creative thinking could come up with a solution. With a bit of ingenuity, I designed a jig that would utilize spring-loaded probes to facilitate connection. This innovative setup allowed me to successfully flash all five Sonoff units to Tasmota without any issues.
