About the Russian woodpecker PCB

Russian woodpecker is an open source Nordic nRF PCB design by openinput-fw, published on GitHub under the CERN-OHL-P-2.0 license. It is a 4-layer board measuring 40 × 30 mm, with 66 components from 29 distinct parts.

Its main chip is the nRF52810-QCxx, from the Nordic nRF family. Other key parts include the MIC5504-3.3YM5, USBLC6-2SC6, ATSAM3U2C and 74LVC3G17. By type, the board carries 35 capacitors, 15 resistors, 5 ICs, 4 connectors, 3 inductors and 2 crystals.

It belongs with the rf & radio designs in this gallery.

Russian woodpecker: common questions

What microcontroller does the Russian woodpecker use?

The Russian woodpecker is built around the nRF52810-QCxx, from the Nordic nRF family.

How big is the Russian woodpecker PCB?

The Russian woodpecker measures 40 × 30 mm, has 4 copper layers and is 1.75 mm thick.

How many components are on the Russian woodpecker?

66 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Russian woodpecker design files?

From the openinput-fw/russian-woodpecker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Russian woodpecker design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which openinput-fw chose for the repository.

Can I test firmware for the Russian woodpecker 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.
