7SEG 3: common questions

What microcontroller does the 7SEG 3 use?

The 7SEG 3 is built around the ATMEGA32-16PU, from the AVR/Arduino family.

How big is the 7SEG 3 PCB?

The 7SEG 3 measures 166.2 × 95.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 7SEG 3?

130 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 7SEG 3 design files?

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

Can I use the 7SEG 3 design in my own project?

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

Can I test firmware for the 7SEG 3 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.
