E28-2G4M20SX SX1281 2.4GHz LoRa SPREAD SPECTRUM 2.4GHz RF transceiver module

[Chip solution]:SX1281

[Operating frequency]: 2.4GHz

[Communication interface]:SPI

[Communication distance]:6km

[Introduction]:E28-2G4M20XX is a 2.4GHz RF transceiver module designed and produced by Ebyte, with a transmission power of 100mW and a long communication distance; it has extremely low current consumption in low-power mode. This LoRa module is a small-volume SMD type (pin spacing 1.27mm), with a high-performance PCB onboard antenna, and uses a 52MHz industrial-grade high-precision low-temperature drift active crystal oscillator; to ensure its industrial characteristics and its stable performance. It can be used for smart homes, security systems, positioning tracking, wearable devices, smart bracelets and health management, etc. It supports RSSI and can achieve in-depth secondary development as needed.
