Two motor: common questions

What microcontroller does the Two motor use?

The Two motor is built around the ARDUINO_NANO_ESP32, from the AVR/Arduino family.

How big is the Two motor PCB?

The Two motor measures 78 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Two motor?

43 components, from 23 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 Two motor design files?

From the owhite/two_motor 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 Two motor design in my own project?

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

Can I test firmware for the Two motor 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.
