Laird's BT900 modules are designed for optimum performance in powered devices and sensors. From the latest CSR 8811 silicon to the power efficient Cortex M3 microcontroller, the BT900 provides maximum design flexibility. Easily balance throughput versus power efficiency, aided by sleep mode triggers to optimise the module's duty cycle. And thanks to the combination of the Cortex M3 and smart BASIC, the BT900 series provides true hostless operation for your product, providing maximum utility while saving you needless costs in your bill of materials.

A smart design is one you don't have to rewrite. Laird's smart BASIC acts as the bridge between software and hardware, enabling an application written for one smart BASIC radio to work on any other. Our event-driven smart BASIC language, unique to the wireless industry, offers built-in functions that replace thousands of lines of C code with a few abstracted lines of smart BASIC. Leverage Laird's years of Bluetooth expertise: write once and deploy anywhere with Laird's line of smart BASIC-ready modules.

Relevant application areas for the BT900 series include industrial cable replacement, medical devices, ePOS terminals and barcode scanners for portable, power-conscious devices, which include those powered by batteries. smartBASIC, an event-driven programming language that allows hostless operation of the module considerably reduces the overall BOM cost of the OEM product. The field proven implementation of smartBASIC from the popular BL600 and BL620 single-mode BLE modules into the new BT900 series allows developers to flexibly utilize smartBASIC applications from those specific modules. This creates various interchangeable BLE applications between the BT900, BL600 and BL620 product ranges.

Laird's BT900 module carries several modular FCC, IC, CE, MIC and Bluetooth SIG approvals, meaning you don't need costly and time-intensive testing to bring certified Bluetooth to market. Certifications from worldwide regulatory bodies take time, effort, financial cost, and ultimately slow development. Laird's approvals extend to your design with no additional testing, making them a fast and efficient route to production.Bluetooth_Smart_Ready_120px
