Board eng: common questions

What microcontroller does the Board eng use?

The Board eng is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How big is the Board eng?

The Board eng measures 53.3 × 68.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Board eng?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Board eng design files?

From the egoraura/jun-eng repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Board eng design in my own project?

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

Can I test firmware for the Board eng 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.
