Slice IAQM: common questions

What microcontroller does the Slice IAQM use?

The Slice IAQM is built around the ARDUINO_NANO_V3.X, from the AVR/Arduino family.

How big is the Slice IAQM PCB?

The Slice IAQM measures 70 × 100 mm, has 2 copper layers and is 1.67 mm thick.

How many components are on the Slice IAQM?

62 components, from 37 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 Slice IAQM design files?

From the feastorg/Slice_IAQM 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 Slice IAQM design in my own project?

Yes, under the terms of its GPL-3.0 license, which feastorg chose for the repository.

Can I test firmware for the Slice IAQM 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.
