About the Rfid PCB

Rfid is an open source PCB design by reportingsjr, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 75 × 50 mm, with 29 components from 19 distinct parts.

Other key parts include the CR95HF. By type, the board carries 15 capacitors, 9 resistors, 2 connectors, 1 IC and 1 inductor.

It belongs with the rf & radio designs in this gallery.

From the project

RFID/NFC board with ethernet+PoE with numerous I/Os.

General ========= This repository has the source for a PCB that uses Power over Ethernet (PoE) to power an STM32F103 microcontroller. It has a 10mbit ethernet MAC/PHY and 3.3V (.6A, 2W) and 12V (.5A, 6W) supplies fed from a 5V (1.8A, 9W) power rail. This gives this board the capability to provide power and control for quite a few different peripherals. The first use of the circuit boards and software in this repository is to provide a lower cost and more versatile RFID based entry method for a local hackerspace, Hive13.
