About the Snak 30 flatfoot PCB

Snak 30 flatfoot is an open source Nordic nRF PCB design by JackMatanky, published on GitHub under the MIT license. It is a 2-layer board measuring 114 × 99.6 mm, with 42 components from 4 distinct parts.

Its main chip is the xiao-ble, from the Nordic nRF family. By type, the board carries 30 diodes, 1 IC and 1 switch.

It belongs with the keyboards, iot & wireless and displays & leds designs in this gallery.

From the project

SNAK (Sisyphus Needed a Keyboard): A split, low-profile, wireless keyboard designed with Ergogen and built with a nice!nano MCU, nice!view OLED, and Kailh choc switches

- The first version would not have been possible without flatfootfox's Let's Design a Keyboard With Ergogen guide. - Later versions were heavily inspired by ceolide's corney-island - Almost all footprints are from infused-kim

Snak 30 flatfoot: common questions

What microcontroller does the Snak 30 flatfoot use?

The Snak 30 flatfoot is built around the xiao-ble, from the Nordic nRF family.

How big is the Snak 30 flatfoot PCB?

The Snak 30 flatfoot measures 114 × 99.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Snak 30 flatfoot?

42 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Snak 30 flatfoot design files?

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

Can I use the Snak 30 flatfoot design in my own project?

Yes, under the terms of its MIT license, which JackMatanky chose for the repository.

Can I test firmware for the Snak 30 flatfoot without the hardware?

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