Micro mouse v2: common questions

What microcontroller does the Micro mouse v2 use?

The Micro mouse v2 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Micro mouse v2 PCB?

The Micro mouse v2 measures 73 × 68.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Micro mouse v2?

26 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Micro mouse v2 design files?

From the prashantbhandary/MicroMouse-LineMaze repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Micro mouse v2 design in my own project?

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

Can I test firmware for the Micro mouse v2 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.
