#dc

Hello everyone, I have a question related to an AC/DC circuit and a microcontroller. The idea is that my PIC microcontroller can detect when the input voltage exceeds 90V. So, I'm thinking of using a bridge rectifier to convert AC to DC, then a voltage divider to step down the voltage, and...

Hi, I have this problem that I can't find the circuit board to identify the burnt component! If someone has a receiver controller like this one could tell me the component reference or if someone knows the component reference for me to replace, I would be very grateful. The brand of my fan...
