Learned new electronics stuff from Erik (thanks!): the H-bridge to control the recirculation flap motor. Trying to squeeze in a prefab module.
From too big (prefab module did not fit) to too small. Despite some great tips from Erik (thanks!) SMD soldering is not in my skillset. After getting the chip more or less installed on a protoype board the motor only worked one way .
Tried yet another driver chip: works this time! But to be honest, at first it did also only work one way. Was a software issue . SMD component would probably work with the new script.
