Sonoff 6 pin Programming clip.
thingiverse
UPDATE. DO NOT USE. The user tested out this clip and the S31 board is too loose to have stable connections on the pins. Without an S31 device to use to model, I cannot correct this. See comment section ......... Sorry. A user requested a 6 pin version because the Sonoff S31 outlet has 6 pins on the serial port connector ( VCC, 2 pairs of RX/TX and then GND). My standard sonoff basic clip only has 5 pins. Print it, put in pogo-pins in , connect to your USB UART TTL adapter and it will hold the pins to the right connectors. The pogo pins I am using are P75-E2 Convex Tip Metal Spring Test Probe Pin, 1.5 mm Diameter.
