Introduction
E22-900T33S is a next-generation LoRa wireless data transmission module based on a SEMTECH high-performance RF chip. It employs spread spectrum technology with TTL-level output, compatible with both 3.3V and 5V IO port voltages. The module adopts next-generation LoRa spread spectrum technology, featuring faster speed, lower power consumption, and a smaller form factor. It supports air wake-up, over-the-air configuration, carrier sense, automatic relay, communication key, and configurable packet length, with custom development services available.
Features
- New LoRa spread spectrum modulation for extended communication range and enhanced interference immunity
- Auto-relay networking support; multi-hop relay for long-distance communication; multiple networks operable simultaneously in the same area
- User-configurable communication encryption key, unreadable once set, greatly enhancing data confidentiality
- LBT support; monitors channel ambient noise before transmission to significantly improve communication success rate in harsh environments
- RSSI signal strength indication for signal quality evaluation, network optimization, and ranging
- Over-the-air parameter configuration; remote configuration or readback of module parameters via wireless command packets
- Air wake-up (ultra-low power mode) for battery-powered applications
- Fixed-point transmission, broadcast transmission, and channel monitoring
- Deep sleep mode with whole-unit current consumption of approximately 4μA
- Supports globally license-free ISM 868/915MHz band
- Integrated PA + LNA; communication range up to 16km under ideal conditions
- Non-volatile parameter storage; module operates with saved settings after power-on
- Efficient watchdog design; automatic restart and recovery with previous parameter settings upon anomaly
- Data rate: 2.4kbps to 62.5kbps
- Supply voltage: 3.3V to 5.5V; performance guaranteed above 5V
- Industrial-grade design for long-term operation at -40~+85℃
Applications
- Smart Home
- Industrial Control
- Smart Agriculture
- Smart City
