Macro keyboard: common questions

What microcontroller does the Macro keyboard use?

The Macro keyboard is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Macro keyboard PCB?

The Macro keyboard measures 80 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Macro keyboard?

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

Where can I download the Macro keyboard design files?

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

Can I use the Macro keyboard design in my own project?

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

Can I test firmware for the Macro keyboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
