MCHPRN4020BCN-V/RM120
Overview
The RN4020BCN-V/RM120 is a fully certified Bluetooth v4.1 Low Energy (BLE) module designed for low-power wireless communication. It integrates a complete Bluetooth stack, a 2.4GHz radio, and an onboard PCB trace antenna into a compact 11.5mm x 19.5mm SMT package. The module features a built-in script engine and supports MLDP for simplified data streaming, making it an efficient bridge between a host MCU and mobile devices.
Why Choose This Part
The module is highly energy-efficient with a 16mA run current and ultra-low sleep modes down to 0.9uA. It simplifies integration by offering a complete onboard stack and integrated antenna, while providing 6 GPIOs and 3 PWM channels for peripheral control without requiring a separate microcontroller in simple applications.
Applications
Key Specifications
Getting Started
Developers can interface with the RN4020 over UART using a standard ASCII command set. For rapid prototyping, use the RN-4020-PICTAIL development board which connects to Microchip Explorer boards. The module supports over-the-air (OTA) firmware updates to ensure long-term field maintainability.
