Help: common questions

What microcontroller does the Help use?

The Help is built around the ProMicro, from the AVR/Arduino family.

How big is the Help PCB?

The Help measures 173 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Help?

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

Where can I download the Help design files?

From the rqcoon/Help repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Help design in my own project?

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

Can I test firmware for the Help 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.
