Introduction
WSN802GDK-A is a RF Evaluation and Development Kit, Boards that enables designers to quickly evaluate and design chipsets in the 2.4 GHz ISM band. In terms of application fields, this board is mainly used for industrial testing, home automation, and military wireless communication systems. In this paper, we will discuss in detail the application field, features, working principle, and some technical specifications of WSN802GDK-A.

Application Fields of WSN802GDK-A
WSN802GDK-A is used for a variety of industrial applications, such as remote control systems, wireless sensor networks, and home automation systems. WSN802GDK-A enables users to quickly and easily evaluate chipsets with a built-in ZigBee network. The ZigBee network supports up to 500 devices on the same network. This capability allows users to quickly develop and test their wireless communication applications without the hassle of setting up a separate network.
Features of WSN802GDK-A
The WSN802GDK-A offers several features:

• Integrated firmware: The pre-loaded firmware on the boards supports several ZigBee profiles and protocols, allowing developers to use predefined functionality and customize their applications.
• Low power and multiple channels: The board can operate in multiple channels and frequencies, which allows for long-range wireless communication without the use of additional power sources.
• Compact and lightweight design: The board has a small form factor, which allows developers to easily integrate it into their applications. The boards are also lightweight, making them easy to transport and install.
• Easy to use: The WSN802GDK-A is designed to be user friendly, and allows developers to quickly develop and test their applications.

Working Principle
The WSN802GDK-A works in accordance with the ZigBee protocol. This protocol is based on the IEEE 802.15.4 standard, which defines the physical and media access control layers of the data link layer of a wireless network. The protocol is designed to be simple and low power, which allows for long-range wireless communication without the need for additional power sources.In a ZigBee network, each device is identified by a unique 48-bit address, which allows the system to identify the node, and to send data to that node. The system is based on a star network architecture, where one device is the star and the other devices are the nodes. Data is broadcast from the star node and received by the node devices.The WSN802GDK-A uses both Carrier-Sense Multiple Access with Collision Avoidance (CSMA/CA) and direct sequence spreading (DSS) techniques for data transmission. The CSMA/CA technique is used to avoid collisions between packets when sending data, while the DSS technique is used to increase the range of the data transmission.Technical Specifications
The technical specifications of the WSN802GDK-A are as follows:

• Communication interface: UART, SPI, I2C, CAN, PWM, GPIO
• Data rate: up to 2 Mbps
• Transmit power: up to 20 dBm
• Working temperature range: -40°C to 85°C
• Dimensions: 32 x 20 mm
• Weight: 6.2 g
• Operating voltage: 2.1V to 3.6V

Conclusion
The WSN802GDK-A is a RF Evaluation and Development Kit, Boards that can be used in a variety of industrial applications. This board is capable of transmitting data at up to 2 Mbps, and it supports up to 500 devices on the same network. The board uses both CSMA/CA and DSS techniques for data transmission, and it is powered by a low voltage source. This board is user friendly and has a small form factor, allowing for easy integration into applications.
