DL-CC2340-A and DL-CC2340-B BLE modules are both designed base on TI's SimpleLink™ wireless series CC2340R5 Bluetooth® Low Energy Chip, which uses a 48-MHz Cortex-M0+ kernel, integrates up to 512 KB of flash memory, 36 KB of SRAM,and has up to 26 universal I/O interfaces. Moreover, these Bluetooth Low Energy modules are equipped with a built-in 48MHz 10PPM external high-speed clock, and 32.768Khz external low-speed clock.

DL-CC1310-B Wireless Module is a SoC Transceiver Module (UART Module) with AT command, which was developed based on Texas Instruments' CC1310F128RHBR RF chip. It combines an integrated RF Controller (Cortex®-MO) and a powerful Arm® Cortex®-M3 Processor, which is ideal to use especially for battery power IoT applications.

DL-LLCC68-S RF module has high receiving sensitivity of -129dBm@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.

DL-SX1278PA is a high power 433Mhz LoRa Transceiver Module, which was developed based on Semtech's RF chip SX1278. For long-range transmission and better coverage concern, a power amplifier (PA) and a low noise amplifier (LNA) are integrated into this LoRa module, which makes its output power up to 30dBm (1W) and receiving sensitivity up to -149dBm

The 868/915Mhz RFM95 Wireless Transceiver Moduless feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

This DL-CC1310-B Wireless Module supports Narrow-band Communication, Direct Sequence Spread Spectrum (DSSS), Long-range Transmission and High-efficiency Communication. Its fully functional AT Commands support any Serial Baud Rate setting from 1920bps to 256000bps, which can greatly improve the communication efficiency with up to -124dBm receiver sensitivity.
