Features： This integrated module is designed using the American Impinj E310 chip. It features an output power range of 0-27dBm. It exhibits excellent reading performance at both short and long distances, and with a 2.5dBi circularly polarized ceramic antenna, it achieves a stable reading distance of 4 meters. It can be widely used in applications such as handheld devices, PDAs with integrated RFID modules, and compact RFID readers. The RF chip uses the Impinj E310 chip. Power output capability By using a PA chip with high conversion efficiency, the PA remains linear even at an output of 27 dBm. The output power enables stable long-distance identification, and in specific applications, the single-tag identification exhibits stronger anti-interference performance. Outstanding tag reading performance Equipped with a 2.5dBi circularly polarized ceramic antenna, the stable identification distance is 4 meters. Multi-tag identification speed: <200 tags/second. Excellent stability Operates 24 hours a day, 365 days a year without crashing. The external design features a shielded casing to reduce conductive and electromagnetic interference. The ceramic and PCB are integrated to dissipate the heat generated by the power amplifier (PA), maintaining stable module output. Simple and efficient hardware and software interfaces The module operates normally with a single 4.5~5V power supply and uses a TTL UART interface for data transmission. Continuous operating current: <800mA @ 5V (27 dBm Output). Standby current: <25mA
