I changed the + and - polarity at SimpleBGC32 board. I have disconnected power in 1/4 second (really fast). The board made a sound like a "tap". The board has no piezo - the sound came from some electrical components.
When the board re-connect properly (right polarity), LEDs are off and the board seems burned - inactive.
When I connect it via USB, the LED lights up and the board is communicating normally (software connects, I see values).
I thought that the board has a: "Reverse-polarity protection, overheat and overcurrent protection"... :-( but I know that it's my fault ..
Can anyone advise me?
Can I claim this?
Or just on the board to replace some parts and will it work?
Is there somewhere board diagram?
Thank you for any help. It is the second board I burned :-( I do not have the money to buy another ... I'm really unhappy ..
