The AES-BCM4343W-M1-G (Avnet BCM4343W SoC Module) is a high performance, highly integrated WiFi and BLE module that provides a programmable ARM® Cortex M4 microprocessor for running user application code. The module is ideal for low power Internet of Things (IoT) enabled sensor and actuator based devices that need wireless connectivity to cloud services. The compact 20 x 35 mm LGA package makes the module a perfect fit for small, embedded applications.
The module is pre-certified, thus minimizing development time and certification costs. The module combines an advanced Broadcom® 2.4GHz 802.11 b/g/n and Bluetooth® 4.1 SoC with 8Mb of serial Flash and a ST Microelectronics STM32F411 ARM® Cortex M4 MCU supporting 512KB Flash and 128KB SRAM. Several of the M4 MCU peripheral functions are made available on the module I/O, allowing for easy connection to user specified interfaces. Advanced security capabilities are available with an optional authentication chip.
The module includes both on-board dual fractal PCB antennas supporting improved RF performance through antenna diversity, and dual coax connectors supporting external antenna connection.
Application development is supported by Cypress's WICED Software Development Kit (SDK), which includes connection to Amazon Web Services (AWS) and IBM® Watson IoT Platform through an intuitive integrated development environment. The starter kit simplifies cloud connectivity for designers in a variety of IoT market segments, including industrial automation, building automation and smart home appliances.
