About the Tiny macropad PCB

Tiny macropad is an open source Nordic nRF PCB design by maker-lukas, published on GitHub. It is a 2-layer board measuring 38.1 × 57.2 mm, with 16 components from 6 distinct parts.

Its main chip is the XIAO-NRF52840-DIP, from the Nordic nRF family. By type, the board carries 7 switches, 6 LEDs, 2 connectors and 1 IC.

It belongs with the keyboards, sensors and iot & wireless designs in this gallery.

Tiny macropad: common questions

What microcontroller does the Tiny macropad use?

The Tiny macropad is built around the XIAO-NRF52840-DIP, from the Nordic nRF family.

How big is the Tiny macropad PCB?

The Tiny macropad measures 38.1 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tiny macropad?

16 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 Tiny macropad design files?

From the maker-lukas/Scroll-Dial 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 Tiny macropad design in my own project?

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

Can I test firmware for the Tiny macropad 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.
