DREAM-3P-CC2340

DL-CC2340-A & DL-CC2340-B Buetooth Low Energy modules were both designed based on the TI SimpleLink CC2340R5 Bluetooth Low Energy device, 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 48-MHz 10-ppm external high-speed clock and 32.768-kHz external low-speed clock.

The DL-CC2340-A Bluetooth Low Energy module can use a variety of universal peripherals for all I/O ports of the CC2340R5 chip, which includes UART, SPI, I2C, timer, temperature sensor, battery voltage detection, built-in analog comparator, and 12-bit ADC analog-to-digital converter. In addition, to meet the security requirements of Bluetooth, it also has AES-128 encryption and RNG functions. Customers can use the SDK for secondary development, and embed its complete applications.

The DL-CC2340-B Bluetooth Low Energy module has a smaller size, but built-in AT commands, which makes it suitable for use as a UART Bluetooth Low Energy module. The external MCU can be connected to the Bluetooth Low Energy module through the UART interface to achieve Bluetooth Low Energy data transmission. 

In terms of RF performance, these CC2340 Bluetooth Low Energy modules integrate an RF balun internally, with simplified RF design, and reduced power consumption. The typical sensitivity can reach as high as -96.5 dBm @ 1 Mbps, and they can also achieve an output power up to +8 dBm. In order to meet the limit standards for RF power in various countries, the power of the Bluetooth Low Energy module can be adjusted (ranging from -21 dBm to+8 dBm).
