Introduction
The E290-xxxTxxS series is a wireless UART module based on the PAN3060 RF chip from Paragon Micro, supporting multiple transmission modes. It operates in two frequency bands: 410.125~493.125MHz and 850.125~930.125MHz, both utilizing ChirpIoT spread spectrum technology with TTL-level output. Built on the next-generation ChirpIoT spread spectrum technology, the module supports half-duplex wireless communication with high interference immunity and high sensitivity. It features over-the-air wake-up, wireless configuration, automatic relay, communication encryption key, AT commands, IAP upgrade, and configurable packet length.
Features
- AT command support for easy configuration
- ChirpIoT-based modulation for extended communication range and enhanced interference immunity
- Automatic relay networking support; multi-level relay for ultra-long-distance communication; multiple networks operating simultaneously in the same area
- User-configurable communication keys, non-readable, ensuring maximum data confidentiality
- RSSI signal strength indication for signal quality assessment, network optimization, and ranging
- Over-the-air parameter configuration via wireless command packets for remote setup or readback of module parameters
- Single-point air wake-up (ultra-low power mode) 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
- E290-400T20S and E290-400T30S support license-free ISM 433MHz band and 470MHz meter-reading band
- E290-900T20S operating frequency: 850.125~930.125MHz, factory default 868.125MHz
- Communication range up to 10km under ideal conditions
- Non-volatile parameter storage; module resumes operation with saved settings after power cycle
- Efficient watchdog design; automatic restart upon anomaly with continued operation using prior parameter settings
- Data rate: 2.4k~62.5kbps
- IAP upgrade support for convenient firmware updates
- Adaptive air data rate; modules configured to any air rate can communicate with each other under certain conditions
- Industrial-grade design for long-term operation at -40~+85℃
Applications
- Home security alarms and remote keyless entry
- Smart home and industrial sensors
- Wireless alarm security systems
