Line follower mainboard: common questions

What microcontroller does the Line follower mainboard use?

The Line follower mainboard is built around the Teensy2.0_(Arduino), from the AVR/Arduino family.

How big is the Line follower mainboard PCB?

The Line follower mainboard measures 95 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Line follower mainboard?

18 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Line follower mainboard design files?

From the GR3Y-SCALE/EGB220-A10 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 mainboard design in my own project?

The repository has no license, so all rights stay with GR3Y-SCALE. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Line follower mainboard without the hardware?

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