Spo2: common questions

What microcontroller does the Spo2 use?

The Spo2 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Spo2 PCB?

The Spo2 measures 75 × 50 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the Spo2?

14 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spo2 design files?

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

Can I use the Spo2 design in my own project?

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

Can I test firmware for the Spo2 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.
