Right design files

The KiCad project lives in the sanoojes/SplitKeeb repository on GitHub; these links point at the commit this page was built from.

Right: common questions

What microcontroller does the Right use?

The Right is built around the NRF52840_HOLYIOT_18010, from the Nordic nRF family.

How big is the Right PCB?

The Right measures 207.2 × 149.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Right?

238 components, from 39 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 Right design files?

From the sanoojes/SplitKeeb 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 Right design in my own project?

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

Can I test firmware for the Right 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.
