KiBot Project Test: common questions

What microcontroller does the KiBot Project Test use?

The KiBot Project Test is built around the STM32G474RET3, from the STM32 family.

How big is the KiBot Project Test PCB?

The KiBot Project Test measures 34 × 28 mm, has 4 copper layers and is 1.651 mm thick.

How many components are on the KiBot Project Test?

31 components, from 15 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 KiBot Project Test design files?

From the nguyen-v/KiBot_Project_Test repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the KiBot Project Test design in my own project?

Yes, under the terms of its MIT license, which nguyen-v chose for the repository.

Can I test firmware for the KiBot Project Test 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.
