Split keyboard Macondo: common questions

What microcontroller does the Split keyboard Macondo use?

The Split keyboard Macondo is built around the XIAO-NRF52840-SMD, from the Nordic nRF family.

How big is the Split keyboard Macondo PCB?

The Split keyboard Macondo measures 145.1 × 182.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Split keyboard Macondo?

84 components, from 6 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 Split keyboard Macondo design files?

From the anton2785-bit/Split_keyboard_Macondo 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 Split keyboard Macondo design in my own project?

The repository has no license, so all rights stay with anton2785-bit. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Split keyboard Macondo 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.
