About the Pockey PCB

Pockey is an open source Nordic nRF PCB design by Hob-dev, published on GitHub. It is a 2-layer board measuring 94.4 × 72.4 mm, with 57 components from 27 distinct parts.

Its main chip is the nRF52840_E73-2G4M08S1C, from the Nordic nRF family. Other key parts include the SRV05-4, BQ24075, 74LVC1G11, MAX17048 and FS8205. By type, the board carries 20 switches, 11 capacitors, 11 resistors, 7 ICs, 3 connectors and 2 inductors.

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

From the project

A play on the word "Pocket", this keyboard is meant to be ultra-portable ultra-low profile using Cherry ULP, with a magnetic enclosure mechanism that let's you fit the keyboard in your pocket. The design is inspired by the Apple Magic Keyboard tilt and feel.

An ultra-low-profile wireless split keyboard built around ultra-thin Cherry MX switches. Pockey follows the Apple Magic Keyboard design philosophy — including the gentle 4° typing tilt — for a slim, unobtrusive desk presence. Each half packs into a closed sandwich: the two halves are magnetically collapsible and snap together when stacked on top of one another, making the whole keyboard pocketable and travel-ready.

Pockey: common questions

What microcontroller does the Pockey use?

The Pockey is built around the nRF52840_E73-2G4M08S1C, from the Nordic nRF family.

How big is the Pockey PCB?

The Pockey measures 94.4 × 72.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pockey?

57 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pockey design files?

From the Hob-dev/Pockey repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pockey design in my own project?

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

Can I test firmware for the Pockey 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.
