Re5-macropad: common questions

What microcontroller does the Re5-macropad use?

The Re5-macropad is built around the ProMicro, from the AVR/Arduino family.

How big is the Re5-macropad PCB?

The Re5-macropad measures 95.3 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Re5-macropad?

7 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Re5-macropad design files?

From the e3w2q/re5-macropad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Re5-macropad design in my own project?

Yes, under the terms of its MIT license, which e3w2q chose for the repository.

Can I test firmware for the Re5-macropad without the hardware?

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