Biodata: common questions

What microcontroller does the Biodata use?

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

How big is the Biodata PCB?

The Biodata measures 28 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Biodata?

53 components, from 28 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 Biodata design files?

From the QuinnFreedman/modular 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 Biodata design in my own project?

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

Can I test firmware for the Biodata 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.
