The KiCad project lives in the Gnoled5660/Macrotype repository on GitHub; these links point at the commit this page was built from.

Macrotype: common questions

What microcontroller does the Macrotype use?

The Macrotype is built around the NRF52840-QIAA-R, from the Nordic nRF family.

How big is the Macrotype PCB?

The Macrotype measures 64.2 × 90.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Macrotype?

57 components, from 32 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 Macrotype design files?

From the Gnoled5660/Macrotype 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 Macrotype design in my own project?

The repository has no license, so all rights stay with Gnoled5660. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Macrotype 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.
