Introduction

The E22-400T33X series is a new generation LoRa wireless module developed based on a high-performance RF chip. It supports multiple transmission modes, operates in the 410.125 to 493.125 MHz frequency band, employs LoRa spread spectrum technology, features TTL-level output, and supports a supply voltage range of 2.3V to 5.5V. Built on next-generation LoRa spread spectrum technology, the module delivers faster data rates, lower power consumption, and a more compact form factor. It supports air wake-up, wireless configuration, carrier sensing, automatic relay, communication key, and configurable packet length, with customized development services available.

Features

• Next-generation LoRa spread spectrum modulation for extended communication range and enhanced anti-interference capability.
• Auto-relay networking support; multi-hop relay for ultra-long-distance communication; multiple networks operable simultaneously in the same area.
• User-configurable communication keys with no read-back capability, greatly enhancing user data confidentiality.
• LBT support — monitors channel ambient noise before transmission, significantly improving communication success rate in harsh environments.
• RSSI signal strength indication for signal quality assessment, communication network optimization, and ranging.
• Over-the-air parameter configuration — remotely configure or read wireless module parameters via wirelessly transmitted command packets.
• Wake-on-Radio (WOR) support for ultra-low power consumption; suitable for battery-powered applications.
• Point-to-point transmission, broadcast transmission, and channel monitoring support.
• Deep sleep mode with whole-unit power consumption of approximately 2uA.
• License-free ISM 433MHz band and 470MHz meter-reading band support.
• Integrated PA+LNA; communication range up to 16km under ideal conditions.
• Non-volatile parameter storage; module operates per configured parameters after power cycle.
• Efficient watchdog design — automatically restarts upon anomaly and resumes operation with previous parameter settings.
• Data transmission rate: 2.4K to 62.5kbps.
• Supply voltage: 2.3V to 5.5V; supply above 3.3V ensures optimal performance.
• Standard design for long-term operation in -40°C to +85°C environments.
• Maximum output power up to 2W for longer and more stable transmission range.
