Handheld: common questions

What microcontroller does the Handheld use?

The Handheld is built around the ATxmega64C3-AU, from the AVR/Arduino family.

How big is the Handheld PCB?

The Handheld measures 240 × 77.7 mm and is 1.6002 mm thick.

How many components are on the Handheld?

113 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Handheld design files?

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

Can I use the Handheld design in my own project?

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

Can I test firmware for the Handheld 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.
