Evaluation and Demonstration Boards and Kits come in a variety of shapes and sizes, but they all serve the same purpose. CYWBDVK001AB is no exception, and this article will discuss the key aspects of its application field and working principle.

CYWBDVK001AB Application Field

The CYWBDVK001AB is an Evaluation and Demonstration Board designed for the development and evaluation of the WLAN/BT combo solutions with the Broadcom BCM43570/BCM4358 chipset. This platform enables users to quickly prototype and develop a smartphone, IoT, home automation, wearables, and automotive connected products.

Core features of this platform are 14x14 mm Wi-Fi/BT combo module supporting 1x1 802.11ac/Bluetooth 5 SoC with a PA, LNA Balun, and a 2.4GHz antenna. This Evaluation Board provides a Wi-Fi antenna including two U.FL connectors for maximum flexibility in routing of RF cables and evaluation of multipath performance. Also, it also has dual-band operation at 2.4GHz and 5GHz.

It has an integrated GPS receiver for accuracy and features an integrated Bluetooth 5 controller with Direct Test Mode (DTM) and Long Range (LR) PHY support. The built-in sensors suite in CYWBDVK001AB includes an 11-axis MEMS sensor plus a comprehensive set of environmental sensors.

CYWBDVK001AB Working Principle

The CYWBDVK001AB uses Broadcom\'s advanced 1x1 802.11ac Wi-Fi/BT combo solution and transceiver. The BCM43570/BCM4358 chipset used in the Evaluation Board provides up to 433 Mbps of physical throughput, plus Bluetooth 5.1 with transmit power of up to +20 dBm.

At the core of the platform is the BCM43602 SoC, which is responsible for the 802.11ac and Bluetooth signal processing, MAC and baseband. This chip supports dual-band operation at both 2.4GHz and 5GHz, with a maximum link rate of up to 433Mbps. It also supports Bluetooth 5.1, with an advanced low power mode and improved RF performance.

The Evaluation Board features an integrated 11-axis MEMS sensor plus a comprehensive set of environmental sensors. The MEMS sensor provides temperature readings, pressure readings, humidity measurements, and accelerometer readings. The environmental sensors measure barometric pressure, temperature, relative humidity and ambient light intensity.

The CYWBDVK001AB also includes a GPS receiver, which is used to provide a highly accurate location and tracking information. The GPS data is used to enable applications such as asset tracking, vehicle navigation, and automated traffic routing.

Conclusion

The CYWBDVK001AB Evaluation and Demonstration Board provides an easy-to-use platform for the development and evaluation of capabilities of the Broadcom BCM43570/BCM4358 chipset. It provides up to 433 Mbps of physical throughput and supports dual-band operation at both 2.4GHz and 5GHz. The integrated 11-axis MEMS sensor, comprehensive set of environmental sensors, and GPS receiver provide the necessary readings and accuracy for asset tracking, vehicle navigation, and automated traffic routing applications.
