Received a M5 ComX GPS module in the post this morning however when I unpacked it I saw signs of heat damage around the pin headers.
And also on one corner of the UBlox chip, along with corrosion marks where the chip in soldered to the board (not very clear in the picture that I cant upload as new users are only allowed 1 media link)
I was going to test the board with a USB - TTL converter however the RX/TX/GND/RST pins are marked the VCC isn’t (there is an unmarked pin next to the GND/RST connectors) but I’m very reluctant to connect up a board that could be subject to a return / replacement.
Could anyone advise on this and also if that unmarked pin is VCC as I will need to know it anyway to complete the project I am working on even if I have to return this board for replacement.
