CopyOfMain: common questions

What microcontroller does the CopyOfMain use?

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

How big is the CopyOfMain PCB?

The CopyOfMain measures 75 × 70.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CopyOfMain?

34 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the CopyOfMain design files?

From the nolanconrad/SeniorDesignProject16 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CopyOfMain design in my own project?

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

Can I test firmware for the CopyOfMain 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.
