Lite design files

The KiCad project lives in the HAM-Key/Lite-layout repository on GitHub; these links point at the commit this page was built from.

Lite: common questions

What microcontroller does the Lite use?

The Lite is built around the nRF52810_module, from the Nordic nRF family.

How big is the Lite PCB?

The Lite measures 61 × 60.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lite?

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

Where can I download the Lite design files?

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

Can I use the Lite design in my own project?

Yes, under the terms of its MIT license, which HAM-Key chose for the repository.

Can I test firmware for the Lite 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.
