Sonoff Mini Programming Clip
thingiverse
The Sonoff Mini presents a significant challenge when attempting to flash custom firmware onto it. This purpose-built programming clip streamlines the process by establishing a secure connection to VCC, Ground, Rx, and Tx with ease. I have already been utilizing a similar setup from Thingiverse, specifically design 2980893, for my Sonoff Basics. Given this experience, I decided to create one tailored to the Mini's specifications. To assemble the clip, you will require four 1mm diameter pogo pins and a spring featuring an internal diameter exceeding 7mm in size. For optimal results, I used an 8mm x 25mm spring that securely grips the board. On the opposite side of the board, the clip leverages the relay and one of the capacitors to ensure precise positioning. If users encounter any issues with a snug fit, I am more than happy to make adjustments as necessary.
