Module Overview

Brief Introduction

• DL-CC1310-B Wireless Module is an SoC-embedded Serial Port RF Transceiver Module (UART Module) with AT command, which was developed by DREAMLNK based on Texas Instruments’ CC1310F128RHBR (built-in dual-core ARM) Radio Frequency chip. It combines an integrated RF Controller (Cortex® -MO) and a powerful Arm® Cortex® -M3 Processor, the Clock Speed of the MCU can reach up to 48MHz.
• This DL-CC1310-B Wireless Module supports Narrow-band Communication, Direct Sequence Spread Spectrum (DSSS), Long-range Transmission and High-efficiency Communication. With its fully functional AT Commands, this CC1310 RF module supports any Serial Baud Rate setting from 1920bps to 256000bps, which can greatly improve the communication efficiency with up to -124dBm receiving sensitivity.
• The embedded software makes this Wireless Module support not only Transparent Transmission Mode, accurate RSSI acquisition, and automatic CCA (Clear Channel Assessment) function, but also High-speed Data Stream and packet Segmentation Transmission, which can effectively reduce the probability of signal collision.
• Moreover, it has defaulted low power consumption software, as well as other muti-functions serial port programs when it is manufactured. A variety of Wireless Baud Rates and functions can be configured, including Long-range Spread Spectrum Mode and Common Mode, Wake-on-Radio (eWOR) function, etc. These different configurations can provide simple and efficient solutions for various long-range communication and IoT applications.
• All these features above make this DL-CC1310-B Wireless Module an excellent RF performance and strong anti-interference in the 860-950MHz frequency band. It combines a flexible, very low-power RF transceiver with a powerful MCU in a platform supporting multiple physical layers and RF standards, which is ideal to use especially for battery power applications. You can also make secondary development based on TI’s development Kit if needed.

Circuit Design

Power Supply Design

• Please pay attention to the power supply voltage of the device, exceeding the recommended voltage range may cause function abnormally and permanently damage;
• Try to use a DC stabilized power supply, and the power ripple coefficient should be as small as possible; the power load when transmitting the maximum power needs to be also considered;
• The module needs to be grounded reliably, and a good grounding can achieve better performance output and reduce the impact of RF on other sensitive devices.

RF Routing Design

• The module should be far away from RF interference sources, such as high-frequency circuit transformers, and it is forbidden to route the wires directly under the module, otherwise, it may affect the receiving sensitivity;
• When using the on-board antenna, the antenna needs to be clear on both sides, and the ground should not be too close to the antenna at the same time, otherwise, it will absorb the radiated energy;  Route 50Ω impedance line lay the ground, and drill more ground holes;
• The PCBA space allows to reserve of a type-matching network, first connecting it through a 0R resistor, otherwise, the antenna is open.

Antenna Design

• There are many types of antennas, choose the appropriate antenna according to your needs;
• Choose a suitable placement position, according to the Antenna polarity, and it is recommended to be vertically upward;
• There should be no metal objects in the antenna radiation path, otherwise the transmission distance will be affected (such as a closed metal casing).
