Mqr speedrunLineFollower: common questions

What microcontroller does the Mqr speedrunLineFollower use?

The Mqr speedrunLineFollower is built around the ESP-01S, from the ESP8266 family.

How big is the Mqr speedrunLineFollower PCB?

The Mqr speedrunLineFollower measures 142.6 × 85.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mqr speedrunLineFollower?

67 components, from 31 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 Mqr speedrunLineFollower design files?

From the MisaelMil/Mqr_speedrunLineFollower 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 Mqr speedrunLineFollower design in my own project?

Yes, under the terms of its GPL-3.0 license, which MisaelMil chose for the repository.

Can I test firmware for the Mqr speedrunLineFollower without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
