The BR-LE4.0-S3A is a standalone Class 1 Bluetooth 4.0 module that requires no firmware or external components. Custom client applications can be written directly onto the module, which supports both analog and digital peripherals, eliminating the need for a second microprocessor. Alternately, the BR-LE4.0-S3A can be integrated into an existing design as a HCI network processor device, with a host processor running the core application and the BR-LE4.0-S3A providing Bluetooth low energy communications.

The BR-LE 4.0-S3A module is equipped with an integrated antenna and is able to run Bluetooth protocols and profiles at low energy and power consumption (2V - 3.6V and 31mA). Each BR-LE 4.0-S3A utilizes the TI CC2541 SoC with 256K Flash (8K RAM), a maximum communicating range of 100m line of site distance, a maximum data rate of 3Mbps, and a frequency band of 2.402GHz to 2.48GHz.

Note: We received these Bluetooth 4.0 modules for a wireless board we ultimately decided to scrap. Therefore, we wanted to at least give you, the customer, the opportunity to use this BR-LE 4.0-S3A in whatever application you’d prefer! Once this module is sold out we will not be ordering it again, get it while you can!
