Pcb: common questions

What microcontroller does the Pcb use?

The Pcb is built around the ATmega328P-P, from the AVR/Arduino family.

How big is the Pcb?

The Pcb measures 50.5 × 41.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb?

13 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb design files?

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

Can I use the Pcb design in my own project?

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

Can I test firmware for the Pcb 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.
