When I wanted to flash the Gosund SP111 sockets with the Tasmota firmware I noticed that all instructions in the net suggest to temporarily solder some pins. This seemed like a lot of work just to load a different firmware on the devices. Besides, it is very cramped; soldering is no fun.
There must be a better way!? Right, we use the Floripointer. With this tool we can, thanks to the spring contacts, simply touch any pin!
Have fun with printing and assembling!
