Sub boards: common questions

What microcontroller does the Sub boards use?

The Sub boards is built around the Raspberry_Pi_5, from the Raspberry Pi family.

How big is the Sub boards PCB?

The Sub boards measures 84 × 108 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sub boards?

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

Where can I download the Sub boards design files?

From the elkel53930/robosweep_twilight repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Sub boards design in my own project?

Yes, under the terms of its MIT license, which elkel53930 chose for the repository.

Can I test firmware for the Sub boards without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
