Nrf51-module: common questions

What microcontroller does the Nrf51-module use?

The Nrf51-module is built around the nRF51x22-QFxx, from the Nordic nRF family.

How big is the Nrf51-module?

The Nrf51-module measures 21.1 × 13.7 mm, has 2 copper layers and is 0.9154 mm thick.

How many components are on the Nrf51-module?

37 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nrf51-module design files?

From the siderakb/nrf51-module repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nrf51-module design in my own project?

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

Can I test firmware for the Nrf51-module 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.
