Motor driver2026a: common questions

What microcontroller does the Motor driver2026a use?

The Motor driver2026a is built around the ATTINY1604-SS, from the AVR/Arduino family.

How big is the Motor driver2026a PCB?

The Motor driver2026a measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Motor driver2026a?

32 components, from 19 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 Motor driver2026a design files?

From the daisuke-ym/motor-driver 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 Motor driver2026a design in my own project?

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

Can I test firmware for the Motor driver2026a 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.
