9.2- x 15.8- x 1.83-mm Bluetooth module supports links up to 50 m

Silicon Labs has introduced a fully integrated, pre-certified Bluetooth module, only 9.2- x 15.8- x 1.83-mm in size, that delivers up to 3 dBm of output power for applications requiring up to a 50 m range.

The Blue Gecko BGM113 module combines a 2.4 GHz Blue Gecko wireless SoC (2.4 GHz transceiver with a 40 MHz ARM Cortex-M4 core, 256kB flash and 32kB RAM) and a high-efficiency chip antenna into a complete, ready-to-use system. BGM113 modules are pre-loaded with Silicon Labs’ Bluetooth 4.1-compliant software stack and are field-upgradable using device firmware upgrades to Bluetooth 4.2 and beyond. The BGM113 module frees developers from complex RF design or protocol decisions, allowing them to focus on the end applications.

As a pre-certified solution, the module minimizes the time, effort and risk required for FCC/CE/IC certifications in North America and Europe and certifications for Japan and South Korea.
The device is supported by Silicon Labs’ Simplicity Studio development platform and wireless software development kit (SDK). Using the familiar BASIC-like syntax of Silicon Labs’ BGScript scripting language, developers can create Bluetooth applications quickly without adding external MCUs to run the application logic. The module draws 8.7mA (peak receive mode) and 8.8mA at 0 dBm (peak transmit mode). It includes a hardware cryptography accelerator supporting advanced AES, ECC and SHA algorithms.
