EBYTE E22-400T30S1B

E22-400T30S is a new generation LoRa wireless module — a wireless UART module based on the SX1268 RF chip. It supports multiple transmission modes, operates in the (410.125 ... 493.125MHz) frequency band (default 433.125MHz), adopts LoRa spread spectrum technology, outputs TTL levels, and is compatible with both 3.3V and 5V IO voltages. E22-400T30S adopts the latest generation LoRa spread spectrum technology. Compared to the traditional SX1278 solution, the SX1268 solution offers longer transmission range, faster speed, lower power consumption, and a smaller form factor. It supports air wake-up, wireless configuration, carrier sensing, automatic relay, communication key, and configurable packet length.

• Developed on SX1268 with new LoRa spread-spectrum modulation technology for extended communication range and enhanced interference immunity
• Auto-relay networking support; multi-level relay for ultra-long-distance communication; multiple networks operable simultaneously in the same area
• User-configurable communication key, unreadable after setting, 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 — remotely configure or read module parameters via wireless command packets
• Wake-on-Radio (WOR) support for ultra-low-power operation, suitable for battery-powered applications
• Point-to-point transmission, broadcast transmission, and channel monitoring support
• Deep sleep mode with whole-unit current consumption of approximately 2uA
• Global license-free ISM 433MHz band support; 470MHz meter-reading band support
• Built-in PA+LNA; communication range up to 10km under ideal conditions
• Non-volatile parameter storage — module operates with saved settings after power cycling
• Efficient watchdog design — automatically restarts upon anomaly and resumes operation with previous parameter settings
• Data rate range: 0.3k~62.5kbps
• Supply voltage: 3.3~5.5V; optimal performance guaranteed above 5V
• Industrial-grade design for extended operation at -40~+85°C
• Dual antenna options (IPEX / stamp hole) for easy secondary development and integration
