Micro mouse v3.0: common questions
What microcontroller does the Micro mouse v3.0 use?
The Micro mouse v3.0 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the Micro mouse v3.0 PCB?
The Micro mouse v3.0 measures 74 × 60.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Micro mouse v3.0?
18 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Micro mouse v3.0 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 v3.0 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 v3.0 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.
