SmartCellAnalyzer: common questions

What microcontroller does the SmartCellAnalyzer use?

The SmartCellAnalyzer is built around the RP2040, from the RP2040/RP2350 family.

How many components are on the SmartCellAnalyzer?

54 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the SmartCellAnalyzer design files?

From the asithniwantha/SmartCellAnalyzer repository on GitHub, which has the schematic and a netlist; the links under Design files point to each one.

Can I use the SmartCellAnalyzer design in my own project?

Yes, under the terms of its MIT license, which asithniwantha chose for the repository.

Can I test firmware for the SmartCellAnalyzer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
