Beschrijving

Een antenne wordt niet bijgeleverd, op de module zit een SMA female connector, men heeft een antenne met een SMA Male connector nodig om te koppelen.

Description

• E49-900T20D is a super cost-effective wireless data transfer module, it has 4 working modes. Each transmission method has its own characteristics and can be applied to different application scenarios. E49-900T20D can perfectly support industrial applications and has undergone rigorous testing in the factory to ensure its industrial reliability and batch consistency.
• E49-900T20D supports a maximum transmission power of 20dBm. Users can set lower output power to save power consumption. The module operates in the frequency band from 850MHz to 930MHz, with TTL level output and compatible with 3.3V IO port voltage.
• The module has data encryption function. The data transmitted by the module in the air is random. Due to the strict encryption and decryption algorithm, data interception is meaningless, the likelihood of interference is reduced, and reliability and transmission efficiency are improved. And it is a cheap wireless serial transceiver module.
• Functions – The measured communication distance can reach 2.5km; The maximum transmission power is 20dB, and the software is multi-level adjustable; Support global license-free ISM868MHz/915MHz frequency band; Support data transfer rate from 1.2Kbps to 200Kbps; Support low power consumption, suitable for battery applications; Support GFSK modulation mode; Support 2. 6V ~ 5. 5V power supply;
• Application scenarios – Portable devices; smart home and industrial sensors; security systems, positioning systems; Wireless remote control, drone; wireless game remote; health products; wireless voice, wireless headset; automotive industry applications.
