Pycom WiPy2.0 board getting heated after powering up

  • Hello,
    I am working on Pycom WiPy2.0 board. Board is getting heat after powering up and i can also hear a small buzzing noise from the board and board is not working. I have tried updating a firmware, safe booted it and also tried it with RS485 for firmware update using UART and power terminals. Unluckily not possible by any way to boot it up. Please do the needful. Thank you.

  • Board was getting power supply through USB coming from laptop. And yes it is getting heated up and i can hear to the buzzing sound coming from the board when i take board closer to my ears.

  • @senapr It may get warm, but not hot. And it should definitely not make any noise. How do you power the board?
