I have some Micro Metal LP gear motors with extended shaft, and the encoder/magnet kit to go with them.
Unfortunately, the terminals on the micro metal LP gear motor are so short, they only barely reach the underside of the encoder board (the motor has a boss around the extended shaft that limits how far down the board can go.)
I couldn’t find a good way to solder the board on there. In the end, I plugged the slots with solder, then heated it and dropped it onto the contacts, and made some kind of connection, but it’s only a little bit of unsupported solder keeping it on there.
Is this how it’s supposed to be? Are my terminals slightly short? Is the boss around the back shaft slightly high? Any advice on making a better connection than essentially dribbling solder on it?
