Pcb: common questions

What microcontroller does the Pcb use?

The Pcb is built around the ATmega32A-P, from the AVR/Arduino family.

How big is the Pcb?

The Pcb measures 381 × 165.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb?

250 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb design files?

From the 0xCB-dev/0xCB-Jupiter 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?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

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.
