RF Evaluation and Development Kits, Boards

BCM920737_LE_KIT is a Bluetooth low energy (BLE) system-on-chip (SoC) development and evaluation kit which enables designers to quickly prototype and create Bluetooth systems. It is manufactured by Broadcom, the worldwide leader in semiconductor solutions for wired and wireless communications. The purpose of the kit is to provide a comprehensive platform for development, testing and demonstration of advanced BLE applications.

Application Field

BCM920737_LE_KIT is designed to be used in the development and evaluation of Bluetooth low energy systems that are intended for use in consumer, health, fitness, industrial, home, and automotive applications. It can be used for the development of a variety of Bluetooth solutions, such as Bluetooth game controllers, hearables, wearables, voice assistants, smart home controls, and other Bluetooth connected devices.

Working Principle

The core of the BCM920737_LE_KIT is the Broadcom Wireless Internet Connectivity for Embedded Devices (WICED) system-on-chip (SoC). This SoC is designed to maximize wireless performance with minimal power consumption. It features a Bluetooth controller, an embedded MCU, an RF radio, and a Bluetooth low energy Protocol stack running on a 32-bit processor. The kit also includes an interactive display, buttons and GPIOs for user input, as well as external interfaces for connecting to an external host computer for application development.

The BCM920737_LE_KIT supports Bluetooth Low Energy profiles such as Proximity, Find Me, Find My Friends, Alert Notification, time and location services, blood pressure monitor, and health thermometer. It also includes a set of application programs and development tools that enable designers to quickly develop and test their solutions. The optional WICED Studio development environment provides an integrated and comprehensive development environment featuring an integrated emulator, graphical editors for hardware and protocol IP configuration, as well as debugging, analysis, and monitoring tools.

The BCM920737_LE_KIT system also includes secure over-the-air (OTA) updates, which enable the user to update the firmware of the device while it is in the field. The OTA feature eliminates the need for users to bring the device back to manufacturing for firmware upgrades as well as reduce the amount of time spent on updating the software. The kit also offers an encrypter/decrypter library and security features such as link encryption and authentication.

In addition, the BCM920737_LE_KIT system includes an integrated power supervisory circuit to monitor the power consumption of the system. The kit has the ability to detect battery and environmental conditions, such as temperature and humidity. The system also provides robust error detection and recovery features such as reset and bus fault detection.

The BCM920737_LE_KIT can be used to develop a variety of projects with the use of the WICED development tools and SDK. The WICED tools and SDK enable the user to easily program and debug their applications in the WICED environment. Additionally, the BCM920737_LE_KIT is also compatible with third-party development tools, such as IAR Embedded Workbench, SEGGER Embedded Studio, and Arm Keil Microcosm.
