As we all know, FSK and LoRa wireless communication are the most widely used IoT technology. As the world's leading supplier of semiconductor products and solutions, Semtech continuously optimizes chips, software and cloud/intelligence based on LoRa technology to develop a complete set of LoRa communication chip solutions, including different LoRa chips for gateways and terminals. DreamLnk, as a professional RF module supplier, also have many Semtech Chip based RF Modules, here is a table just FYI:

Today, I would like to highlight one of our LoRa Core™ LLCC68 based RF module: DL-LLCC68-S LoRa Module. First of all, let's take a look at some features of this LLCC68 chip:

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 highly efficient integrated power amplifier, SX1261 chip can transmit up to +15 dBm signal, while LLCC68 chip can transmit up to +22 dBm signal.

DL-LLCC68-S Pin Definitions

So, is there any other reason for us to choose this LoRa Core™ LLCC68 RF module?

1.   Max. transmit power of DL-LLCC68-S can reach +22dBm

2.   It supports both LoRa and FSK modes (-125dBm@FSK, -129dBm@LoRa); compared with traditional Sub-1Ghz wireless module, the FSK mode of DL-LLCC68-S is more sensitive

3.   DL-LLCC68-S LoRa mode supports improved performance and solutions, which has stronger anti-interference ability.

4.   The transmission rate of DL-LLCC68-S is 1.76K ~ 62.5K, which is a significant improvement

5.   DL-LLCC68-S LoRa mode's sleep power consumption is as low as 2uA, with stronger performance than SX1278 but lower power consumption

*  The most important is: the supply of LLCC68 chips is more stable than other LoRa chips.

*  Co-channel supperssion of 19dB in LoRa Mode

*  Built-in bit synchronizer for clock recovery

*  Automatic Channel Activity Detection (CAD) with ultra-fast AFC

*  Supported bandwidth: 125kHz, 250kHz, 500kHz

    BW = 125kHz supports SF5-SF9

    BW = 250kHz supports SF5-SF10

    BW = 500kHz supports SF5-SF11

LLCC68 & SX126X LoRa Chip

Based on LoRa Core™ LLCC68 chip, this DL-LLCC68-S RF Module can meet a variety of wireless transmission needs in the market. 

Typical application:

*  Existing FSK wireless communication 

*  LoRa-based smart home applications

*  Industrial control scenarios that require anti-jamming, remote and real-time performance

*  The original LoRa applications doesn't need ultra-distant scenes

*  Smart Home, Smart Community, Consumer Electronics
