  • Hello, I want to use this break out board conected directly with a micro controller PIC18F4550 is there anything i should do different from the example schematic? execp for the part that i wont use and FTDI because I want to use the uart directly ?? thanks

  • I have a problem with the module using this board, when I connect TX of the micro to RX of the gsm module it power ups the module and dont know why ¿? and I can’t communicate with the module, I already desolder the jumpers and still isn’t working. Can anyone help me?

  • And what about the flow control pins? the problem I have is that i cannot communicate with the module using the usart of the pic18f4550. I send “AT” and nothing happens is like its not receiving anything

  • is it absolutly necesary desolder the jumpers of the TX and RX by USB to use the break out pins with a microcontroller? ‘cause i’m trying to comunicate with the micro using this pins and I cant.

No public wish lists :(
