► Core technical advantages

1. MCU based on Arm® Cortex® -M33 core, compared with Cortex-M3 core, M33 core improves performance by nearly 20%. 2. NXP's current MCU series with outstanding power consumption: Under the condition of 96MHz, it can reach 32uA/MHz dynamic power consumption. 3. Accessible security: The main platform MCU executes from encrypted images (internal flash) real-time through the trust and configuration based on SRAM PUF, and through the TrustZone-M protection mechanism. 4. Achieve new breakthroughs in performance and efficiency: The main platform MCU provides integrated power management IC (DC-DC) and dedicated co-processors for core signal processing and encryption acceleration. 5. Comprehensive products and scalability: The main platform MCU has a 40nm low-cost advantage, and provides a wide range of expandable Connectors on the development board. 6. You can use a PC to connect to play sound effects through the USB audio driver. 7. Controllable RGB LED (this LED contains the driver) Display. If you need to expand the number of LEDs, you can connect the Brightek solution light board made by WPI through the J19 connector on this solution board. Lights, billboards, TV walls... etc.
