NFCScanner: common questions

What microcontroller does the NFCScanner use?

The NFCScanner is built around the 98-00241-2, from the RP2040/RP2350 family.

How big is the NFCScanner PCB?

The NFCScanner measures 80 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NFCScanner?

37 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the NFCScanner design files?

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

Can I use the NFCScanner design in my own project?

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

Can I test firmware for the NFCScanner 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.
