About the TypePak PCB

TypePak is an open source Nordic nRF PCB design by JackMatanky, published on GitHub under the MIT license. It is a 2-layer board measuring 51.7 × 32 mm, with 10 components from 8 distinct parts.

Its main chip is the xiao-ble, from the Nordic nRF family. Other key parts include the 74HC595. By type, the board carries 3 connectors, 3 capacitors, 2 ICs and 2 inductors.

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 TypePak is a custom keyboard controller PCB housed inside of an aftermarket Game Boy Advance cartridge shell. It features Bluetooth connectivity, ZMK support, a low-power monochrome display, a built in LiPo battery, 9 GPIO pins, and 8 dedicated output pins. Simply slot the TypePak into a keyboard with a compatible Game Boy cartridge slot, flip the power switch, and you've got yourself a working wireless keyboard. (After flashing the appropriate firmware and keymap, naturally.)

TypePak: common questions

What microcontroller does the TypePak use?

The TypePak is built around the xiao-ble, from the Nordic nRF family.

How big is the TypePak PCB?

The TypePak measures 51.7 × 32 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the TypePak?

10 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the TypePak design files?

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

Can I use the TypePak 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 TypePak 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.
