Smart Module Integrates BTLE Stack With Or Without MCU

Bluetooth 4.1 Low Energy module, pre-loaded with a Low-energy Data Profile, carries both worldwide regulatory certifications and Bluetooth SIG certification.

Microchip’s new RN4020 Bluetooth 4.1 Low Energy (BTLE) module, carrying both worldwide regulatory certifications and Bluetooth SIG certification, is pre-loaded with a Low-energy Data Profile (MLDP), enabling streaming any type of data across the BTLE link. The stack-on-board module can connect to any microcontroller with a UART interface, or it can operate standalone for basic data collection and communication, such as a beacon or sensor. The standalone operation, facilitated by unique no-compile scripting, allows module configuration via an ASCII command interface. The module provides a built-in PCB antenna with 7 dBm transmit power and a receive sensitivity of -92.5 dBm, enabling operation over 100 m in a compact form factor of only 11.5 x 19.5 x 2.5 mm. Target markets include home automation and appliances, wearable devices, remote controls, pulse and proximity sensor-based systems, and industrial applications. The RN4020 BTLE module is available today for $6.78 each/1,000. The RN-4020-PICtail flexible BTLE PICtail/PICtail Plus daughter board, available now for $49, enables code development via USB interface to a PC, and over the onboard In-Circuit Serial Programming interface for Microchip’s PICkit or MPLAB REAL ICE tools.
