BT900-SA

## BT900 Series - Bluetooth v4.0 Dual Module **Powerful, Intelligent BT in a Tiny Form Factor** 

## **SMALL. SMART. SIMPLE.** 

Laird’s BT900 modules reduce the engineering burden and design risk of integrating Bluetooth and Bluetooth Low Energy into any OEM device.  The BT900’s tiny form factor, optimized power schemes and smartBASIC language provide a secure, stable Bluetooth environment for any embedded design.  Let Laird’s innovative BT900 series and decades of expertise in Bluetooth module design speed your product to market. 

## **FLEXIBLE FOR ANY CHALLENGE: A COMPLETE SOLUTION** 

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 smartBASIC, the BT900 series provides true hostless operation for your product, providing maximum utility while saving you needless costs in your bill of materials. 

## **EMBEDDED BLUETOOTH MADE EASY** 

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

## **– GLOBAL APPROVALS MAKE YOURSELF AT HOME.** 

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.
