MotorDriver3: common questions

What microcontroller does the MotorDriver3 use?

The MotorDriver3 is built around the Arduino_Pro_Mini, from the AVR/Arduino family.

How big is the MotorDriver3 PCB?

The MotorDriver3 measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MotorDriver3?

11 components, from 10 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 MotorDriver3 design files?

From the aliaafee/robot-platform 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 MotorDriver3 design in my own project?

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

Can I test firmware for the MotorDriver3 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.
