DL-LLCC68-S is a wireless module designed based on Semtech 's radio frequency chip LLCC68 . It mainly adopts a new generation of LoRa™ modulation technology for ultra long distance spread spectrum communication. This LoRa module is compact in size, and has the characteristics of ultra low receiving power consumption, strong anti interference ability, and longer transmission than traditional modulation methods. It can be widely used in various wireless communication fields of the Internet of Things.


DL-LLCC68-S RF module has high rece iving sensitivity of 129dB m@LoRa, ultra low receiving current and dormant current, the transmit power can be configured through software, and the maximum power can reach +22dBm. Compared with traditional modulation technology, LoRa™ modulation technology has obvious advantages in anti blocking and selection, which solves the problem of distance, anti interference and power consumption that traditional design schemes cannot take into account at the same time.


LoRa Smart Home (LLCC68) is a Sub-GHz LoRa® RF Transceiver for medium range indoor and outdoor wireless applications. This LLCC68 chip uses SPI interface and is pin-to-pin compatible with SX1262. With efficient integrated power amplifier, SX1261 chip can transmit up to +15 dBm signal, while LLCC68 chip can transmit up to +22 dBm signal.


Advantages of this LoRa Core™ LLCC68 RF module:


*  LLCC68 RF module supports both LoRa and FSK modes

*  Compared with traditional small wireless products, the FSK mode of LLCC68 is more sensitive

*  The LORa mode of LLCC68 supports better performance and Solutions

*  The most important is: the supply of LLCC6 chips is more stable than other LoRa chips.


Features:


*  Supports FSK, GFSK, MSK, GMSK and LoRa™ modulation mode;

*  Frequency range: 150~960MHz; 433Mhz, 868Mhz, 915Mhz optional

*  Maximum 151dB link budget

*  The operating voltage is 3.3V, the maximum output transmission power is + 22dBm, and the maximum operating current is 130mA.

*  The receiving state has the characteristics of low power consumption, with a minimum receiving current of 4.5mA, and a standby current of 0.6mA.

*  Integrated DC-DC Converter and LDO

*  Programmable bit rates from 1.76 Kbps to 62.5 kbps @ LoRa, and 300 kbps @ FSK

*  High sensitivity-129dBm@LoRa;
