Sonoff B1 V2 bulb programming adapter
thingiverse
Programming adapter for the Sonoff B1 R2 bulb based on the inspiring work of AphexFX who created the model for the B1 R1. The holes are working for me with pogo pins with spring contacts P75-B1 diameter 1.02 mm. The spring contacts help to balance uneveness of the contact points.
