Solarcast Geiger Module: common questions

What microcontroller does the Solarcast Geiger Module use?

The Solarcast Geiger Module is built around the nRF52832, from the Nordic nRF family.

How big is the Solarcast Geiger Module?

The Solarcast Geiger Module measures 92 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Solarcast Geiger Module?

40 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Solarcast Geiger Module design files?

From the Safecast/Solarcast repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Solarcast Geiger Module design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Solarcast Geiger 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.
