NuMaker-M5531

M5531 Series

The M5531 series microcontrollers feature an Arm® Cortex®-M55 core running at up to 220 MHz, equipped with Arm® Helium™ DSP technology for enhanced digital signal processing capabilities. These MCUs integrate up to 2 MB of Flash Memory and 1.5 MB of SRAM, and support the HYPERBUS™ interface for external memory expansion. Operating at voltages from 1.7V to 3.6V and temperatures from -40°C to +105°C, the M5531 series is well-suited for demanding industrial environments.
They are ideal for compute-intensive embedded applications such as real-time signal processing, high-performance control systems, sensor fusion, smart factory automation, medical devices, and communication systems.

NuMaker-M5531 Development Board

NuMaker-M5531 is a development platform built on the NuMicro® M5531 series microcontroller. This development board integrates essential system components and a wide range of peripheral interfaces, helping accelerate system design and the evaluation of prototyping.

The NuMaker-M5531 target board provides Arduino UNO-compatible headers, multiple GPIOs, and common communication interfaces such as I2C, UART, and SPI. The onboard Nu-Link2-Me debugger and programmer supports the SWD interface, enabling both online and offline programming, as well as in-chip debugging. It also outputs debug messages to a PC via a virtual COM port (VCOM). In addition, the built-in status LED displays programming status in real time. The Nu-Link2-Me module is detachable and can be used independently as a production programming tool.
