NuMaker-GestureAI-M55M1 for Local AI in AIoT Devices

The NuMaker-GestureAI-M55M1 is a development platform that brings local AI processing to the microcontroller level for AIoT applications. Based on Nuvoton’s NuMicro M55M1 series, the board combines an Arm Cortex-M55 running at up to 220 MHz with an Arm Ethos-U55 Micro-NPU, creating a foundation for energy-efficient embedded AI designs with local inference.

With AI performance of up to 110 GOPS, the platform addresses AIoT scenarios in which data needs to be processed directly at the endpoint instead of being sent to the cloud first. This is especially relevant for intelligent devices, sensor hubs, smart appliances, and other embedded systems where response time, energy efficiency, and system integration all matter.

The board is designed for applications that combine local signal processing, sensing, and machine learning. These include human presence detection, intelligent audio applications, AIoT endpoints, robotics, smart toys, and sensor hubs. This makes the platform well suited for developers who want to validate AI functions early and transition them into compact, resource-efficient device architectures.

To support this, the NuMaker-GestureAI-M55M1 provides up to 1.5 MB of on-chip RAM, 2 MB of flash, and expansion options via OctoSPI and HyperBus. It also offers extensive interfaces including USB High-Speed OTG, Ethernet MAC, CAN FD, I3C, I2C, SPI/I2S, UART, SDIO, DMIC, and a camera capture interface controller. On-board features include a MEMS microphone, Micro SD card slot, HS-USB OTG, user buttons, LED, and a CMOS module.

For secure AIoT designs, the platform also supports features such as Secure Boot, TrustZone, TRNG, Key Store, crypto acceleration, XOM, flash write protection, and PSA Level 2. This makes the board suitable not only for endpoint AI evaluation, but also as a solid development basis for secure and energy-efficient AIoT devices.
