Microchip RN4020 Bluetooth Smart (BLE) Module 2.44 GHz Low Energy UART Control RN4020-V/RM120

Microchip RN4020-V/RM120 is a high-performance Bluetooth Smart (BLE) module designed for seamless integration into wireless communication applications. This module operates at a carrier frequency range of 2.402 GHz to 2.480 GHz within the ISM band and supports Bluetooth 4.1 Low Energy standard, ensuring compliance with modern wireless protocols.

Equipped with a complete Bluetooth stack and Microchip Low-Energy Data Profile (MLDP), the RN4020 provides comprehensive support for Bluetooth SIG profiles with enhanced custom data capabilities. Control is achieved via a straightforward ASCII command set over UART, simplifying the development and integration process.

The module features a compact castellated surface mount form factor measuring 11.5 x 19.5 x 2.5 mm, making it suitable for space-constrained designs. Its low power consumption, facilitated by operating voltages from +1.8 V to +3.6 V DC (typical 3.3 V), caters to battery-powered and low-power applications.

Internal scripting capabilities allow the module to operate independently without a host processor in simple use cases. The device also supports device firmware upgrades via UART or over-the-air to keep the module up-to-date with new features and security enhancements.

Security is ensured with AES128 encryption, and the module can be software configured to function in various Bluetooth roles including peripheral, central, client, or server. Multiple IO pins provide flexible control and status monitoring, along with an integrated PCB antenna for reliable wireless performance.

The RN4020 achieves a RX sensitivity of -92.5 dBm at 0.1% bit error rate and offers a maximum data rate of 1 Mbps, making it suitable for a range of industrial, commercial, and STEM education wireless projects. Environmental specifications include a wide temperature range from -30°C to 85°C.
