Line follower car: common questions

What microcontroller does the Line follower car use?

The Line follower car is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Line follower car PCB?

The Line follower car measures 167.1 × 181.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Line follower car?

24 components, from 23 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 Line follower car design files?

From the varaddeshpande15/line-follower-car 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 Line follower car design in my own project?

The repository has no license, so all rights stay with varaddeshpande15. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Line follower car 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.
