VIBRATION VM522

VM522 is a read/write card module compliant with ISO/IEC 14443 Type A/Type B protocols, operating in 13.56MHz HF mode. It features high integration and ultra-low power consumption, making it particularly suitable for contactless card data transmission applications that require high performance while pursuing low cost. Additionally, the module incorporates an onboard UART interface and an SPI interface for communication with the NFC chip, which greatly facilitates performance evaluation and secondary development.

The VM522 operates at a supply voltage of 3.3/5.0V with a reception distance of 8~10cm. The module supports LPCD low-power mode, in which the average operating current can be as low as 1.5uA. The module dimensions are 70.0mm × 45mm.
