Espruino and Adafruit Fingerprint sensor

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.
