New product post - MFRC522 Module

During one week, we have continually updated four blogs about new products, no matter the Shield Matrix ,  the Ultrasonic Sensor And Temperature Switch, or the Key Pad Shield, Semiconductor Refrigeration Tablet, which one is your most favorable product and enable you to create and complete an innovative project? If not, maybe you can refer to our up-coming MFRC522 Module, an contactless reader module based on the MFRC522 from NXP B.V. Have a look.  


It is an contactless reader module based on the MFRC522 from NXP B.V.. Communication Via Serial makes it simple and easy-using. Compatible with ISO/IEC 14443 A/MIFARE cards, it supports all variants of the MIFARE Mini, MIFARE 1K, MIFARE 4K, MIFARE Ultralight, MIFARE DESFire EV1 and MIFARE Plus RF identification protocols, and the operating distance in Read/Write mode is up to 40 mm. This module could be used in a variety of applications: Access management, Tracking of goods, Tracking of persons and animals, Toll collection and contactless payment, Machine readable travel documents, Smartdust (for massively distributed sensor networks), Tracking sports memorabilia to verify authenticity, Airport baggage tracking logistics and etc.

Note: MFRC522 IC working voltage of 3.3V, the power to the module, do not mistake the input voltage!
