CE-PiicoDev-RFID-Reader-Writer: common questions

What microcontroller does the CE-PiicoDev-RFID-Reader-Writer use?

The CE-PiicoDev-RFID-Reader-Writer is built around the RP2040, from the RP2040/RP2350 family.

How big is the CE-PiicoDev-RFID-Reader-Writer PCB?

The CE-PiicoDev-RFID-Reader-Writer measures 25.4 × 52 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CE-PiicoDev-RFID-Reader-Writer?

37 components, from 27 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 CE-PiicoDev-RFID-Reader-Writer design files?

From the enolf/CC3501-project-hardware 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 CE-PiicoDev-RFID-Reader-Writer design in my own project?

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

Can I test firmware for the CE-PiicoDev-RFID-Reader-Writer 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.
