Title: Cab you use a Adafruit Trinket to use an AEKII with USB?
Post by: Komendar on Fri, 19 August 2016, 21:58:33

Hi everyone,
Just made an account to ask this and hopefully become a regular. So I might get a working AEKII for free soon and as it's ADB i have to make it work with usb somehow. There's a ton of documentation on the teensy 2.0 but it costs like 20 bucks here in europe and i can get a  Adafruit Trinket for about the half of that.

Will the Teensy software work on the Trinket? If so are the solder points the same and should I get the 3v or 5v Trinket? Thanks!

The trinkets use controllers that do not have built in USB controllers.

The cheap arduino pro micro clones can be used to replace a Teensy, they have the same ATMEGA32U4 chip, but less pins available, 18 instead of 25 on the Teensy 2.0. Be prepared for the much more difficult flashing process described here:
