2 serial ports on Electron - possible


#1

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

How about consulting the docs first?
https://docs.particle.io/reference/device-os/firmware/electron/#serial

The Electron has two (actually three) independent and free serial ports (Serial1, Serial4 and Serial5 - 2 & 3 are occupied)
