Gruzik2.0: common questions

What microcontroller does the Gruzik2.0 use?

The Gruzik2.0 is built around the STM32F103C8T6, from the STM32 family.

How big is the Gruzik2.0 PCB?

The Gruzik2.0 measures 128 × 39.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Gruzik2.0?

35 components, from 21 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 Gruzik2.0 design files?

From the NYDEREK/LineFollower_GRUZIK2.0-light 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 Gruzik2.0 design in my own project?

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

Can I test firmware for the Gruzik2.0 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.
