Introduction
E220-400T22D adopts the latest generation LoRa spread spectrum technology, a wireless serial module designed based on the LLCC68 chip solution. It supports multiple transmission modes, operates in the 410.125 to 493.125MHz frequency band, uses TTL level output, and is compatible with 3.3V and 5V IO port voltages.
Features
- New LoRa spread spectrum modulation technology based on LLCC68, with excellent communication range and interference immunity
- User-configurable communication key (non-readable), enhanced data confidentiality
- LBT support: monitors channel noise before transmission, improving success rate in complex environments
- RSSI signal strength indication for signal quality assessment, network optimization, and ranging
- Over-the-air wake-up for ultra-low power consumption, suitable for battery-powered applications
- Point-to-point, broadcast, and channel monitoring transmission modes
- Deep sleep mode with total power consumption of approximately 5μA
- Built-in PA and LNA, communication range up to 5 km under specified conditions
- Parameter retention after power-off, resumes operation with configured settings on power-up
- Efficient watchdog design: auto-restart on anomaly, resumes operation with previous parameters
- Bit rate: 2.4k to 62.5kbps; supply voltage: 2.3 to 5.5V; industrial-grade design for long-term use at -40 to +85℃
Applications
- Home security alarms and remote keyless entry
- Smart home and industrial sensors
- Wireless alarm and security systems
- Building automation solutions
- Wireless industrial remote control
