Overview

The MDBT42V-P512KV2 is a high-performance Bluetooth v5.4 transceiver module based on the Nordic nRF52832 SoC. It features an integrated ARM Cortex-M4 CPU with a floating-point unit (FPU), 512kB of Flash, and 64kB of RAM, all contained within a compact 29-SMD package with an integrated PCB trace antenna. This module supports both BLE and 2.4GHz proprietary RF protocols, making it a versatile choice for power-sensitive wireless designs.

Why Choose This Part

The module excels in power efficiency, consuming only 0.3uA in shutdown mode and featuring multiple sleep states with RAM retention down to 0.7uA. Its integrated PCB trace antenna and pre-certified design reduce RF layout complexity and accelerate time-to-market. With a 64MHz Cortex-M4 core and diverse serial interfaces like I2S and PWM, it handles complex application logic without an external microcontroller.

Applications

Wearable Health Monitors
Utilizes the ultra-low power consumption and integrated FPU for real-time sensor data processing in fitness trackers and heart rate monitors.
Smart Home Nodes
Acts as a reliable Bluetooth 5 interface for lighting controllers, smart locks, and environmental sensors requiring long battery life.
Industrial IoT Sensors
Facilitates wireless data transmission in factory environments using its wide 1.7V to 3.6V supply range and multi-protocol 2.4GHz radio.
Wireless HID Devices
Ideal for low-latency peripherals like wireless mice, keyboards, and remote controls using either BLE or proprietary 2.4GHz modes.

Getting Started

Developers should use the Nordic Semiconductor nRF5 SDK or the newer nRF Connect SDK, which supports the Zephyr RTOS. Debugging is typically performed via the SWD interface using a J-Link programmer. Raytac provides the MDBT42V-DB development board to break out the 29-SMD pins for breadboarding and rapid prototyping.

Also Consider

MDBT42Q-512KV2 Raytac - A slightly larger form factor version that provides more GPIO access while maintaining the same nRF52832 core.
