Regards EmbeddedStore **Q: ? It is work in raspberry pi** A: Yes, the RC522 RFID card reader module can work with a Raspberry Pi. The RC522 module communicates with the Raspberry Pi over SPI (Serial Peripheral Interface) protocol. To use the RC522 module with a Raspberry Pi, you will need to connect the module to the Pi's SPI interface, which consists of the MOSI (Master Out Slave In), MISO (Master In Slave Out), SCK (Serial Clock), and CS (Chip Select) pins. You can refer to the datasheet or manual of the RC522 module to know which pins are used for SPI communication. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Kit for Electronics and Programming Projects *by A***A on 9 January 2023* I purchased it for my son. He has been using it for various projects and it has been working great. The kit comes with everything he needs to get started and he was able to set it up easily. he was able to start experimenting with it right away. I like that it is a high quality product that is easy to use and has a lot of potential for different projects. ### ⭐⭐⭐⭐ good *by P***R on 13 March 2021* good ### ⭐⭐⭐⭐⭐ A compact MFRC522 reader *by G***N on 7 October 2019* This is a 13.56MHz RFID reader, so first of all check your cards because the older 125kHz is a completely incompatible system. Though the MFRC522 chip has 3 interfaces (SPI, UART, I2C), here the SPI mode is hardwired, so the 'SDA' pin in fact means NSS. There is quite a good quickstart here: https://uc0c9cd294a4fe55929d522701c8.dl.dropboxusercontent.com/cd/0/inline2/Ap8J6qpkMylK6-eT-bFEqzgr3kjQeReDYcAOB-O3_WRcv_b5cPuScaL3JWrz206l8rpV8P14dCqfa0hAmOLWGyE3MLVCQZm8f_n86Qm8I1O_208ElqDi6kpAUXakRhxQjOkP6c3ChuiavDg-t4mn5rQnzkCzi4l9YnzLkhLOtV5tE9O_l72Debneo1-jjgGTILZVBUd0P0IXXBilOZHnw224jwF75bvJiepbDzNUL33TEwJN3XoflcCJj6dLblVCXuMvomlauGBu0SqnwkLJPMMZ7ju1JpmbGX4tWBki7-uaNFHLnmRZnFRgRDnxoH8PChrphGhPSi3rOcxRB9zjI9jJ/file And the full documentation of the chip here: https://www.nxp.com/docs/en/data-sheet/MFRC522.pdf ## Frequently Bought Together - Arduino RC522 RFID Card Reader Module Kit - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno R3 ATmega328P with USB Cable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/256144575-rc522-rfid-card-reader-module-kit-for-arduino](https://www.desertcart.com.br/products/256144575-rc522-rfid-card-reader-module-kit-for-arduino) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-16*
