Packing list

• 2pcs Lora1121 RF Modules

One module hardware is including three frequency band, 2.4Ghz and S Band (1900~2200Mhz) and ISM Band frequency.

2.4Ghz and S Band (1900~2200Mhz) are default on the board, you only need to choose one frequency band of ISM Band (433Mhz,470Mhz,868Mhz,915MHz)

for example

• If you choose 433Mhz, the module will come with three frequency band: 433Mhz, 2.4Ghz and S Band
• If you choose 470Mhz, the module will come with three frequency band: 470Mhz, 2.4Ghz and S Band
• If you choose 868Mhz, the module will come with three frequency band: 868Mhz, 2.4Ghz and S Band
• If you choose 915Mhz, the module will come with three frequency band: 915Mhz, 2.4Ghz and S Band

The LoRa1121 module utilizes SEMTECH's LR1121 chip, an ultra-low-power, long-range transceiver that supports both global ISM band and 2.4GHz communication. The LoRa1121 supports LoRa and (G)FSK modulation in the sub-GHz and 2.4GHz bands, as well as Sigfox® modulation in the sub-GHz band, and long-range frequency hopping spread spectrum (LR-FHSS) in the sub-GHz, 1.9-2.1GHz, and 2.4GHz ISM bands. The LR1121 complies with the physical layer requirements of the LoRaWAN® specifications released by the LoRa Alliance®, while remaining highly configurable to meet the needs of various applications and proprietary protocols.
