8-led output: common questions

What microcontroller does the 8-led output use?

The 8-led output is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How big is the 8-led output PCB?

The 8-led output measures 120.3 × 83.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 8-led output?

19 components, from 5 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 8-led output design files?

From the pbrowne011/pcb 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 8-led output design in my own project?

The repository has no license, so all rights stay with pbrowne011. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 8-led output 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.
