Specified 5V in but tested with 3.3V, the built in LDO does not interfere with 3.3V setups. I used MFRC522_I2C library (just needed assign a dummy pin for resetPowerDownPin in the constructor since it’s not exposed on this board) ## Features - Broad Microcontroller Compatibility: Seamlessly integrates with Arduino, ESP32, and Raspberry Pi platforms, ensuring flexibility for various development projects. Docs: github.com/nulllaborg/rfid - Flexible Automatic Reading Modes: Features three user-selectable automatic reading modes: Automatic Card ID (UID) Reading, Automatic Block Data Reading, and a Combined Reading Mode, streamlining data acquisition from RF media. - Standard High Frequency Operation: Operates at the industry-standard frequency of 13.56MHz, and is compatible with various RF media types, including RFID tags, key fobs, coin cards, and standard white cards. - Low-Power I2C Communication: Utilizes the efficient I2C protocol, address 0x28, simplifying wiring and reducing pin count. The module features low power consumption with a sleep current of <80uA and a typical operating voltage of 5V. - Compact and Efficient Design: size (56mm x 40mm), making it ideal for space-constrained projects. Its peak current is limited to <100mA, ensuring reliable and safe operation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0G2L7LQD7 | | Best Sellers Rank | #1,678 in Single Board Computers (Computers & Accessories) | | Brand | NULLLAB | | Built-In Media | 1 x RFID Module | | Compatible Devices | Arduino, ESP32, Raspberry Pi | | Connectivity Technology | I2C, Ph2.0 | | Customer Reviews | 5.0 out of 5 stars 2 Reviews | | Included Components | 1 x RFID Module | | Manufacturer | Kongxiang Laboratory Technology (Shenzhen) Co., LTD | | Number of Items | 1 | | UPC | 716842604770 | | Unit Count | 1 Count | | Warranty Description | 2 Year Manufacturer | ## Product Details - **Brand:** NULLLAB - **Compatible Devices:** Arduino, ESP32, Raspberry Pi - **Connectivity Technology:** I2C, Ph2.0 - **Included Components:** 1 x RFID Module - **Number of Items:** 1 ## Images ![RFID Module – RC522, 13.56MHz, I2C Protocol, Compatible with Arduino, ESP32, Raspberry Pi, Supports Automatic Card/Data Reading, with Ph2.0 to Dupont Cable & Blank White Card - Image 1](https://m.media-amazon.com/images/I/61Eu+GsZ3sL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by J***S on August 1, 2026* Works great.
