Espruino and Adafruit Fingerprint sensor

Posted on
  • Hi Gordon,
    I'm a software developer but I'm kinda novice in term of electronic.

    Do you think that this fingerprint sensor could be used on the Espruino board ?
    https://www.adafruit.com/products/751#Te­chnical_Details
    (some examples at http://learn.adafruit.com/category/biome­tric)

    It is using TTL Serial and I think I've read that Serial can be used on Espruino board (via usb converter) ?

    Could you please tell me if this is feasible ?

    Thanks,
    Chris

  • Hi Chris,

    Yes, it sounds like it can be used just fine and will wire straight on. You don't need a USB-TTL converter - that's if you want to connect Espruino to a PC, but don't want to use the on-board USB socket.

    Adafruit also made an Arduino Library for it - while you can't use the library in Espruino, it shows how simple the reader is to use (just a few bytes of data to send). You should be able to get it running pretty quickly.

  • Thanks Gordon :)
    I will then order one and see what can be done.
