Introduction
E220-400T30S is a wireless serial module featuring the LLCC68 chip, operating at 410.125~493.125MHz (default 433.125MHz), with TTL-level output compatible with both 3.3V and 5V IO port voltages. Compared to traditional SX1278-based solutions, it offers longer transmission range, higher speed, lower power consumption, and a smaller form factor. Supported features include air wake-up, wireless configuration, carrier sense, auto-relay, communication key, and sub-packet length configuration. A notable advantage is that the LLCC68 covers a wider frequency range.
Features
- LLCC68 LoRa chip delivers lower power consumption, longer communication range, and stronger anti-interference capability
- Tested communication range up to 10km
- Maximum transmit power 30dBm, software-adjustable multi-level
- Supports user-configurable unreadable encryption keys, greatly enhancing user data privacy
- Wireless parameter configuration via wireless command packets for sending or remotely reading module parameters
- Air wake-up (ultra-low power feature) for battery-powered application solutions
- Supports fixed transmission, broadcast transmission, and channel monitoring
- Supports globally license-free ISM 433MHz and 470MHz bands for worldwide meter reading
- Parameters saved automatically on power-off, resumes operation with previous settings on power-up
- Effective watchdog design — automatically restarts upon anomaly and resumes operation with previous parameters
- RSSI support for signal quality assessment, improving communication networks and ranging
- LBT support — monitors channel ambient noise before transmission to improve communication
- Supports air data rate 2.4kbps~62.5kbps
- Supports 2.3V~5.5V power supply; performance guaranteed above 5.0V
- Industrial-grade design, supports continuous operation at -40~85℃
- Dual antenna options (IPEX and stamp hole) for easy secondary development and integration
Applications
- Home security alarms and remote keyless entry
- Smart home and industrial sensors
- Wireless alarm security systems
- Building automation solutions
- Wireless industrial remote control
