The features of SL031 are identical as SL030 except for communication interface that IIC is for SL030 and SL031 uses UART. Developed based on NXP's low power transponder ICs, HF RFID module SL031 is a small MIFARE reader/writer, Supporting MIFARE™ Classic 1K, MIFARE™ Classic 4K, MIFARE Ultralight™; Applicable for 13.56MHz; Embedded module; Auto Real-time detecting tag which moves into or out of detective range and reports through one output pin's logic level; All necessary components integrated with antenna in one PCB. The maximum working current and sleep current are 45mA and 10uA respectively, First choice for the applications which requires low power consumption.
