Handheld control: common questions

What microcontroller does the Handheld control use?

The Handheld control is built around the ATmega32U4, from the AVR/Arduino family.

How big is the Handheld control PCB?

The Handheld control measures 176 × 72.8 mm, has 2 copper layers and is 1.6002 mm thick.

How many components are on the Handheld control?

102 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Handheld control design files?

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

Can I use the Handheld control design in my own project?

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

Can I test firmware for the Handheld control 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.
