Led matrix board: common questions

What microcontroller does the Led matrix board use?

The Led matrix board is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How big is the Led matrix board?

The Led matrix board measures 117 × 58.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Led matrix board?

95 components, from 13 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 Led matrix board 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 Led matrix board 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 Led matrix board 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.
