Rotor test: common questions

What microcontroller does the Rotor test use?

The Rotor test is built around the C2052951, from the AVR/Arduino family.

How big is the Rotor test PCB?

The Rotor test measures 18 × 15 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rotor test?

7 components, from 5 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 Rotor test design files?

From the lbligh/enigma-iib-lzb23 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 Rotor test design in my own project?

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

Can I test firmware for the Rotor test 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.
