Arduino Uno RFID Kit

Arduino Uno RFID Kit – Rapid Prototyping for Smart Access Control

The kit combines the ubiquitous Arduino Uno STM32 board with an MFRC522 13.56 MHz RFID reader/writer module, pre‑wired for instant integration. Designed for makers, robotics, and industrial IoT, it delivers seamless NFC communication via SPI and offers up to 10 Mbps data transfer – enough for high‑speed tag reading and smart badge applications. With on‑board level shifting, the module runs flawlessly on the Uno’s 5 V supply, eliminating the need for additional logic converters.
Its compact 8 mm × 8 mm footprint, 10 byte FIFO buffer, and voltage‑ripple tolerant design make it ideal for embedded projects, while the robust shielding and selectable RF power settings help comply with regional regulations. The included libraries and example sketches expedite development into ready‑to‑run devices.
