Combat: common questions

What microcontroller does the Combat use?

The Combat is built around the Arduino_Nano_ESP32, from the AVR/Arduino family.

How big is the Combat PCB?

The Combat measures 73.4 × 41.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Combat?

17 components, from 14 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 Combat design files?

From the mkhrenov/openhell 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 Combat design in my own project?

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

Can I test firmware for the Combat 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.
