Hello together,
I have a broken hand-held transmitter from RUKU - SF 433-1 Mini/M, 433,920 - of a garage door opener. He is operating with 12V Battery. I tried to build the transmitter in my car and run it with 13.6 volt DC.
Then the small SMD part broke down.
Actually i found a lot of voltage regulators in the web, but they all have different pinnings and layouts.
I took some meassurements on the PCB of the transmitter and painted the wiring of my SMD part.
Something like a voltage regulator from 12V DC to ?? volt for the separate signal board which produce the 433.920 MHz signal.
Does anyone can give a tip?
Kind regards,
