Ebyte E80-400M2213S LR1121 410~493MHz/2.4GHz LoRa Dual-band Wireless RF Transceiver Module

Ebyte E80-400M2213S LR1121 410~493MHz/2.4GHz LoRa Dual-band Wireless RF Transceiver Module

E80-400M2213S is a dual-band SMD LoRa hardware SPI wireless module independently developed based on SEMTECH's LoRa Connect™ LR1121 chip for multi-band global connectivity, with transmit powers of 22dBm and 13dBm respectively. An industrial-grade 48MHz high-precision low-temperature drift crystal oscillator is integrated inside the module. LR1121 is SEMTECH's third-generation ultra-low power LoRa transceiver. It provides multi-band LoRa and long-range frequency hopping spread spectrum (LR-FHSS) communications based on Sub-GHz and 2.4 GHz ISM bands, as well as satellite s-band connectivity. At the same time, it remains configurable to meet different application requirements and proprietary protocols.
