About the PMK Dongle C nRF HW00 PCB

PMK Dongle C nRF HW00 is an open source Nordic nRF PCB design by PumaFPV, published on GitHub under the MIT license. It is a 6-layer board measuring 11.6 × 7.2 mm, with 17 components from 10 distinct parts.

Its main chip is the NRF52840-CKAA-F-R7, from the Nordic nRF family. By type, the board carries 10 capacitors, 2 inductors, 2 resistors, 1 IC, 1 connector and 1 antenna.

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

From the project

PMK - Full wireless split keyboard

The goal is to make a suit of wireless devices such as "smart keyboard" (combined mouse and keyboard), gamepad, LEDs, knobs, display, etc The first step is to make a wireless split keyboard, and then we will see later...

Currently, you can connect up to 8 (software limited) devices per dongle, each of them having up to 8 (software limited) layers. Layers only affect keyboards and LED.

PMK Dongle C nRF HW00: common questions

What microcontroller does the PMK Dongle C nRF HW00 use?

The PMK Dongle C nRF HW00 is built around the NRF52840-CKAA-F-R7, from the Nordic nRF family.

How big is the PMK Dongle C nRF HW00 PCB?

The PMK Dongle C nRF HW00 measures 11.6 × 7.2 mm, has 6 copper layers and is 0.8464 mm thick.

How many components are on the PMK Dongle C nRF HW00?

17 components, from 10 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 PMK Dongle C nRF HW00 design files?

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

Can I use the PMK Dongle C nRF HW00 design in my own project?

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

Can I test firmware for the PMK Dongle C nRF HW00 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.
