Zesty25: common questions

What microcontroller does the Zesty25 use?

The Zesty25 is built around the ARDUINO_PRO_MICRO, from the AVR/Arduino family.

How big is the Zesty25 PCB?

The Zesty25 measures 96.5 × 96.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Zesty25?

87 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Zesty25 design files?

From the Gtrx0/zesty25 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Zesty25 design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which Gtrx0 chose for the repository.

Can I test firmware for the Zesty25 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.
