About the Ahokore PCB

Ahokore is an open source Nordic nRF PCB design by dezlidezlidezli, published on GitHub under the Custom license license. It is a 2-layer board measuring 265.7 × 103.8 mm, with 98 components from 24 distinct parts.

Its main chip is the YJ-18010, from the Nordic nRF family. Other key parts include the AP2112K-3.3TRG1 and TP4054. By type, the board carries 40 diodes, 38 switches, 9 resistors, 4 capacitors, 3 ICs and 1 transistor.

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

From the project

Ahokore is a 36-key one-piece split keyboard, with full wireless functionality.

Ahokore is a 36-key one-piece split keyboard, with full wireless functionality. Stagger is copied from the Ferris, as I found that very comfortable. The name is "wireless" translated into Maori.

V1 is tested to be fully working, and uses a nice!nano.

V2 has been tested and is fully working, and a small group-buy has been run. Extras will be available within a few weeks (written on 30/6/21), on store.dez.li.

Ahokore: common questions

What microcontroller does the Ahokore use?

The Ahokore is built around the YJ-18010, from the Nordic nRF family.

How big is the Ahokore PCB?

The Ahokore measures 265.7 × 103.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ahokore?

98 components, from 24 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ahokore design files?

From the dezlidezlidezli/ahokore repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Ahokore design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Ahokore 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.
