About the Rfid hub PCB

Rfid hub is an open source RP2040/RP2350 PCB design by sebastian-lenz, published on GitHub under the MIT license. It is a 2-layer board measuring 46 × 61 mm, with 8 components from 4 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 4 connectors, 2 switches, 1 IC and 1 LED.

From the project

The RFID Hub is a C++ project designed to utilize the Raspberry Pi Pico microcontroller to interface with up to four RFID readers. Each RFID reader acts as a unique keyboard input, allowing users to simulate keystrokes by presenting RFID tags to the readers.

This project uses Platform.IO, please visit https://platformio.org/ to find out more. After installing Platform.IO this project can be build using the following command:

Rfid hub: common questions

What microcontroller does the Rfid hub use?

The Rfid hub is built around the Pico, from the RP2040/RP2350 family.

How big is the Rfid hub PCB?

The Rfid hub measures 46 × 61 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rfid hub?

8 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rfid hub design files?

From the sebastian-lenz/rfid-hub repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rfid hub design in my own project?

Yes, under the terms of its MIT license, which sebastian-lenz chose for the repository.

Can I test firmware for the Rfid hub 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.
