- enough keys for placing on base layer all letters for extended alphabets (alphabets with more than 26 letters). - plenty of keys for playing with different variants to find your best setup. - one keyboard for all operating systems. Switch between settings for different operating systems with a shortcut (currently settings for Linux and Windows are implemented). - used AT90USB1286 with 128 KB memory. No limits for storing settings. - wide choice of keycaps. The keyboard is designed for maximum use of keycap sets from standard…

Jeaex left: common questions

What microcontroller does the Jeaex left use?

The Jeaex left is built around the Teensy++2.0_(C), from the NXP family.

How big is the Jeaex left PCB?

The Jeaex left measures 166.6 × 145.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jeaex left?

72 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Jeaex left design files?

From the osenchenko/jiaex repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Jeaex left design in my own project?

Yes, under the terms of its GPL-3.0 license, which osenchenko chose for the repository.

Can I test firmware for the Jeaex left without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
