SumoBot v1: common questions

What microcontroller does the SumoBot v1 use?

The SumoBot v1 is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How big is the SumoBot v1 PCB?

The SumoBot v1 measures 88 × 60 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the SumoBot v1?

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

Where can I download the SumoBot v1 design files?

From the choicebuilds/SumoBot-v1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SumoBot v1 design in my own project?

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

Can I test firmware for the SumoBot v1 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.
