Main board v1: common questions

What microcontroller does the Main board v1 use?

The Main board v1 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Main board v1?

The Main board v1 measures 268 × 55.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main board v1?

47 components, from 21 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Main board v1 design files?

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

Can I use the Main board v1 design in my own project?

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

Can I test firmware for the Main board v1 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.
