Overview
Specimen Track HF RFID Reader Module is a product with UART and IIC serial port. It has various functions and supports multi-ISO or IEC standard contactless card. The RF protocol is complex. The design combined some frequently user command of RF card and then user could operate the cards with full function by sending simple command to the module. The impedance between RF module and antenna was tuned by impedance analyzer. Also, the module has excellent performance and stability. The module and antenna is split design with 4 wires are linked the antenna and module. Normally the wire should be less than 200mm, or it will affect the module’s performance and stability.
