LM55X
Overview
LM55X Evaluation Product FamilyFor LM961 Bluetooth® Dual Mode Module
The LM55X is the evaluation product family for the LM961 Bluetooth® Dual Mode module. A great starting point for evaluating Bluetooth® applications. Simplifying the development process and cutting down time to the production phase.
LM assists the developer to create new applications with the LM961 module. The LM55X product family helps the developer to integrate the LM961 into their hardware designs and test for production. The LM55X evaluation board enables the developer to evaluate a Bluetooth® Dual Mode application.
The LM55X is USB powered or powered from a coin cell battery when operating the prototype in a “real world” scenario. The LM55X is Arduino compatible, providing the option of connecting the LM961 to an Arduino Board. The Arduino providing the power supply when connected.
