Snackymini Keyboard

Inspired by MiniVan Arrow Layout http://www.keyboard-layout-editor.com/#/gists/174470794149140f43dd6c9b544c168c

I have included the snackymini-manufacturing-submission.zip file containing all of the gerber files needed so you can send it to the manufacturer directly.

Ater having the PCB printed, you can use Arduino IDE (with Teensyduino installed) to compile the code in firmware folder, then upload it to your Teensy.

Snackymini keyboard: common questions

What microcontroller does the Snackymini keyboard use?

The Snackymini keyboard is built around the Teensy3.2, from the NXP family.

How big is the Snackymini keyboard PCB?

The Snackymini keyboard measures 257.8 × 94 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Snackymini keyboard?

91 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Snackymini keyboard design files?

From the huytd/snackymini-keyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Snackymini keyboard design in my own project?

The repository has no license, so all rights stay with huytd. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Snackymini keyboard 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.
