Self Balancing Bot: common questions

What microcontroller does the Self Balancing Bot use?

The Self Balancing Bot is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the Self Balancing Bot PCB?

The Self Balancing Bot measures 120 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Self Balancing Bot?

11 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Self Balancing Bot design files?

From the Shantu-2580/Prototypes repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Self Balancing Bot design in my own project?

The repository has no license, so all rights stay with Shantu-2580. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Self Balancing Bot without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
