ArdubroFX Mini Cornetto Trilogy

Three flavours of DIY ArdubroFX Mini :

1. A Pro Micro version with alternate wiring. No extra components, but only works with "alternate wiring" Arduboy FX games.

2. A Pro Micro version with regular wiring (recommended). This needs a PNP transistor and a couple of resistors. Works with all Arduboy FX games.

3. A Teensy 2.0 version. No extra components and works with all Arduboy FX games.The Teensy 2.0 can be expensive but is currently available on AliExpress.

The cases can be found on TinkerCad : https://www.tinkercad.com/things/adXmE7xeBoh-ardubrofx-cases?sharecode=M6hAKYIe7hGurcEeC_LspZqAEC3WvNS60JpF3JN1SpM

Notes: The only USB C Pro Micro that will work is a black PCB version with components on the reverse. You can use a regular Micro USB pro Micro. The TinkerCad files will allow you to alter the case design should you need to move holes, or make any alterations. I used a 1.54 inch 7PIN White OLED with SSD1309 display driver. There are some 1.54 inch screens out that where the PCB is bigger and will require sanding down.

*Update (26-02-2025): 1.54 inch OLED with SSD1309 drivers seem hard to find. The TZT ones I used no longer seem to have SSD1309 drivers. Unless you can find a SSD1309 1.54inch screen only use this project for reference!

You need to program the Pro Micro or Teensy 2.0 with a bootloader before soldering it to the PCB. I used instructions from the following projects :

I'm on Youtube under " Megazoid's Hut " There are some video on these ArdubroFX Mini's if you are interested

**** The BOM file will show ALL the componants from all three projects ***  - Some parts like the screens came from AliExpress.
