The D-Robotics RDK X3 dev board is specifically designed for edge AI applications, particularly in robotics. It utilizes the Sunrise X3 processor with a quad-core Arm Cortex-A53 CPU and a dual-core BPU (Brain Processing Unit) that features a 5 TOPS NPU for AI tasks. This makes it suitable for computer vision applications like object detection and image segmentation. Key features include 2GB or 4GB of RAM, a 40-pin GPIO for compatibility with Raspberry Pi accessories, and various connectivity options like Gigabit Ethernet and Wi-Fi/Bluetooth. The board supports Ubuntu and ROS, providing a robust platform for developers to create and deploy AI-powered robotics solutions.

previously we have written about various development boards including the MYD-LD25X, the Sparkfun Pro Micro-RP2350, the Boardcom RK3576 and many more feel free to check those out if you are interested in the topic.
