  1. rmerlob (verified owner)

    I bought a couple of these GPRS relay boards that I have not been able to make them work.
    They DO NOT get connected to the arduino IDE.
    Apparently they came with out bootloader.

  2. Chao (store manager)

    Dear customer,

    We just checked our stock, all have bootloader.

    1.Please double check the wiring. see image here: https://twitter.com/electro_phoenix/status/1138290433480519680

    2. Make sure you choose correct board, it should be pro mini 5V/16M.

    The programming guide is product description, please double check.
