AI Self-Balance Robot: common questions

What microcontroller does the AI Self-Balance Robot use?

The AI Self-Balance Robot is built around the J_MCU ->STM32G474, from the STM32 family.

How big is the AI Self-Balance Robot PCB?

The AI Self-Balance Robot measures 130 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AI Self-Balance Robot?

56 components, from 34 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the AI Self-Balance Robot design files?

From the SteveZC8537/AI_Self-Balance_Robot repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the AI Self-Balance Robot design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which SteveZC8537 chose for the repository.

Can I test firmware for the AI Self-Balance Robot without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
