E32-433T20D V8 SX1278 3km 433MHz LoRa Module

E32-433T20D V8 SX1278 3km 433MHz LoRa Module

The E32-433T20D V8 SX1278 3km 433MHz LoRa Module is a wireless serial port module with a LoRa solution (TTL level), transparent transmission mode, operating in the 410-441MHz frequency band (default 433MHz), and using LoRa spread spectrum technology.

Datasheet

Application Areas

• Home security alarm and remote keyless entry.
• Smart home and industrial sensors.
• Wireless alarm and security systems.
• Building automation solutions.
• Wireless industrial-grade remote control.
• Healthcare products.
• Advanced meter reading architecture (AMI).

Features

• Using next-generation LoRa spread spectrum modulation technology, longer communication distance and stronger interference suppression suna.
• Supports AT command, easier to use
• Supports FEC forward error correction to improve communication stability.
• Supports the global license-free ISM 433MHz frequency band.
• Supports users to set the communication key and cannot be read, greatly improving the confidentiality of user data.
• Supports LBT function and monitors channel environment noise before transmission, which can greatly increase the module's communication success rate in harsh environments.
• Supports RSSI signal strength indicator function to evaluate signal quality, improve communication network and range.
• Supports fixed-point transmission, broadcast transmission, and channel monitoring;
• Supports deep sleep, the power consumption of the whole machine is about 3 uA;
• Under ideal conditions, the communication distance can reach 3 km;
• Parameters are saved, and the module can store the set It operates according to the parameters;
• Supports data transmission speeds from 2.4K to 19.2K bps.
• Supports 2.7 to 5.5V power supply; more than 5V power supply can provide the best performance.
• The maximum module power is 100mW (20dBm), and transmission is farther and more stable.
