RS232 5V input 5v signal

Posted on
  • Hello!

    Can i connect RS232 to Espruino and receive data with 5V signal??

  • Yes, that's fine if you're using a 5v-capable pin.

    Have a look here. You can use any pin that doesn't have 3.3v written by it. As it happens, all of the USARTs are 5v capable so you're fine - but it's worth checking that page every time you connect a 5v signal.

  • So, i can, for example, connect RX to C11 and all will be work?

    pin (ะก11) will not burn?

  • Absolutely, that'll be fine. As long as it's a 5v signal.

  • Thanks, Gordon!
