RF Evaluation and Development Kits, Boards are essential components for testing and developing RF applications. EK43703-01 is a popular model of these kits, which combines evaluation and software development into a single package. It is an evaluation board for Zigbee RF4CE compliant applications.

EK43703-01 Application Field and Working Principle

EK43703-01 is intended for use in a variety of Zigbee-enabled commercial and residential applications such as lighting control, remote control, home automation, energy management, telemetry, and medical monitoring fields. It is particularly suitable for excellent low-power consumption and real-time control capacity features.

It contains the NXP Semiconductors QN9080C and QN9078C Bluetooth Low Energy Systems-on-Chip (SoC) and the QN4412RF4CE radio transceiver. The operating frequency of QN9080C and QN9078 is 2.4 MHz, and the operating frequency of QN4412RF4CE is 2402 - 2480 MHz. This evaluation board also comes with an integrated design featuring a 32-bit ARM Cortex-M0+ core, preloaded with the Zigbee RTOS stack. It also includes integrated SYS/BIOS real-time operating system, a capacitive touch user interface library, an LCD display driver library, performance analyzers, power measurement tools, wireless protocol analyzers, and a debug interface.

The QN9080C and QN9078C come with on-board Flash memory and SRAM. The Flash memory contains the Zigbee RTOS stack pre-programmed into the system. This allows for faster development, testing, and evaluation. It also allows for an easier implementation of Zigbee-based applications from the start. The SRAM is used for storing variables, data, and code.

In terms of working principle, the QN9080C and QN9078C SoCs contain the necessary peripherals for Zigbee-based applications. These include a UART, SPI, I2C, DMA, and GPTimer controllers. The QN4412RF4CE radio transceiver includes an internal 32-bit ARM Cortex-M0+ core, allowing for the necessary timing accuracy required for Zigbee operation. The radio transceiver also contains a high-frequency voltage-controlled oscillator (VCO) for frequency band selection, and a tunable voltage-controlled oscillator (VCO) for frequency selection. The radio transceiver also contains a programmable attenuator to enable adjustment for best performance. Lastly, QN4412RF4CE radio transceiver contains a built-in temperature-compensated amplifier for maximum signal strength at the antenna.

The evaluation board also includes an on-board debugger and emulator, enabling users to test and debug their applications without the need for external hardware. Additionally, the board features a pin header connector, allowing for easy connection to external hardware. This board also includes a number of on-board radio test modules, providing users with a range of diagnostic functions.

Query performance and stability of the RF signal can be monitored through the on-board Ethernet port. Data can also be transferred between the board and a laptop or desktop computer through the Ethernet port. Data can be transferred between the board and a Zigbee-enabled device using the included QN4412RF4CE radio transceiver.

The EK43703-01 evaluation board provides an extensive suite of tools for both the design and development of Zigbee-based applications. It includes a wide range of features such as a UART, SPI, I2C, DMA, GPTimer controllers, a radio transceiver, and a built-in temperature-compensated amplifier. The board also features a number of on-board radio test modules and a pin header connector, enabling users to easily connect to external hardware. Lastly, the board provides users with a performance analyzer, power measurement tool, wireless protocol analyzer, and a debug interface.

The EK43703-01 evaluation board is a convenient and powerful tool for Zigbee-based applications. Its intuitive and user-friendly design makes it easy to use and its pre-programmed Zigbee RTOS stack allows for rapid development and testing. Its on-board radio test modules and USB port provide quick and efficient transfer of data. With its integrated design, the board enables users to develop high-performance, reliable Zigbee-enabled applications quickly and easily.
