Line-Follower-Robot v2: common questions

What microcontroller does the Line-Follower-Robot v2 use?

The Line-Follower-Robot v2 is built around the STM32F103C8T6, from the STM32 family.

How big is the Line-Follower-Robot v2 PCB?

The Line-Follower-Robot v2 measures 78 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Line-Follower-Robot v2?

42 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Line-Follower-Robot v2 design files?

From the minhle4397/Line-Follower-Robot-v2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Line-Follower-Robot v2 design in my own project?

The repository has no license, so all rights stay with minhle4397. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Line-Follower-Robot v2 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.
