Main board: common questions

What microcontroller does the Main board use?

The Main board is built around the Arduino_Nano_v2.x-MCU_Module, from the AVR/Arduino family.

How big is the Main board?

The Main board measures 40.6 × 82.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main board?

32 components, from 25 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 Main board design files?

From the ARTS-Laboratory/Sensor-Package-Access-Hub 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 Main board design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which ARTS-Laboratory chose for the repository.

Can I test firmware for the Main board 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.
