hi
i have been tasked with a project to create a mobile fingerprint reader (time and attendance) i can get quite a nice fingerprint reader that does all the recognition and template storage. and just sends back some Serial strings. now i know that the electron has 1 serial port, but i need a touch screen i was thinking of the Nextion series (for enrolling users ect) but i need a second serial port for that. or does anyone else know of a nice touch screen that can be used with the particle? big enough for fat fingers to use. the particle is a brilliant device and will work very well. your suggestions as always are much appreciated. thanks Gary
