Cgranja-Pelec: common questions

What microcontroller does the Cgranja-Pelec use?

The Cgranja-Pelec is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Cgranja-Pelec PCB?

The Cgranja-Pelec measures 37 × 41 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cgranja-Pelec?

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

Where can I download the Cgranja-Pelec design files?

From the Croco41/RENDU_BOOTCAMP_ELEC_CGRANJA repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Cgranja-Pelec design in my own project?

The repository has no license, so all rights stay with Croco41. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Cgranja-Pelec 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.
