Hello,
I have a seeeduino lorawan with gps board. Unfortunately while debugging I connected the battery in reverse polarity to the board while it was connected with the laptop via USB, and the lights on the board went off. I think the baord has stopped working now as there are no lights. Is there any way to fix the board again by replacing any component? Is there a fuse or something which I can replace?
If you connect the board and non of the led blinks (even for a millisecond) and/or stays on you can assume the board is damaged. Buy a new one unless you have a lot of experience and proper soldering-tools repairing.
Hi mihir.r.93
maybe it is good choice for you to power through USB. if it is not useful you should get a new.
