The D-Robotics RDK X3 development board is designed for edge AI applications and features a Sunrise X3 quad-core Arm Cortex-A53 processor running at 1.5GHz with a dual-core BPU (Brain Processing Unit) with 5 TOPS of edge inference capability. The board includes a 40-pin GPIO interface, ensuring compatibility with Raspberry Pi 4B accessories for versatile project development.
The RDK X3 offers 2GB or 4GB of LPDDR4 RAM and includes a MicroSD card slot for storage expansion. Designed for real-time applications like robot control and intelligent monitoring, its 5 TOPS inference capability makes it ideal for computer vision workloads such as object detection, body segmentation, scene parsing, etc…
Previously, we covered the Horizon X3 AI development board, which uses the same Horizon Robotics Sunrise X3 processor. We’ve also written about several other edge AI development boards, including the Synaptics Astra Platform SL1680, SagireEdge AI 600, and MYiR Tech’s MYC-LR3568. Feel free to explore them if you’re interested.
