Ultra low-power Bluetooth Smart module eases development

Mouser is now offering the BGM111 Blue Gecko Bluetooth Smart Module from Silicon Labs. The ultra low-power, Bluetooth 4.1 (Bluetooth Smart) module is designed for applications where good RF performance, ultra-low power consumption, and easy development are main design factors. With TX power up to 8dBm, RX sensitivity down to -93dBm, and up to 200 meters range, the BGM111 has best-in-class RF performance and can provide long-range, robust Bluetooth Smart connectivity. The Silicon Labs BGM111 Blue Gecko Bluetooth Smart Module, available from Mouser Electronics, integrates Bluetooth radio, an antenna, Bluetooth Smart software stack, and GATT-based profiles, and includes the Profile Toolkit, which allows designers to create additional GATT-based services. The BGM111 also includes a 32-bit ARM Cortex-M4 processor and can host end-user applications, which eliminates the need for an external microcontroller in devices with size, price or power constraints. The BGM111 Bluetooth Smart module has flexible hardware interfaces - including UART, SPI, and I²C - to connect to different peripherals or sensors. The module offers up to 25 GPIO with interrupts, four 12-bit analog-to-digital converters (ADCs), one 12-bit digital-to-analog converter (DAC), an internal temperature sensor, autonomous hardware crypto accelerator, and an integrated DC-DC buck converter. The module has a wide input voltage range, from 1.8V to 3.8V, enabling engineers to power wireless system designs from a single 3V coin cell battery or two AAA batteries. Mouser Electronics is also shipping the Silicon Labs SLWSTK6101A Bluetooth Smart Module Wireless Starter Kit. This starter kit features an on-board J-Link debugger, a virtual COM port interface, an LCD display and a humidity/temperature sensor and test points to access all the pins of the Blue Gecko Bluetooth Smart Modules. The WSTK6101A Wireless Starter Kit is supplied with an expansion board (BRD8006A Add-on Board) that can be connected to the WSTK mainboard expansion header. The expansion board contains additional peripherals such as an accelerometer, buttons, LEDs, joystick, and an I²C expansion slot. The Silicon Labs BGM111 Blue Gecko Bluetooth Smart Module targets low-power, wireless applications, such as sports and fitness tracking, health and medical devices, Internet of Things (IoT) connectivity, and home and factory automation, says the company.
