Why Choose RK3588 and RK3568 Development Boards for Controlling Drones?
Drones, also known as unmanned aerial vehicles (UAVs), have applications across military and civilian sectors. From aerial photography and agriculture to disaster rescue and power line inspection, drones have become indispensable. Traditionally, drones relied on modular designs with separate flight control systems and additional expansion modules. This approach, while versatile, is not ideal for managing weight, particularly in smaller drones. Thus, using highly integrated SoCs (System on Chips) like RK3588 and RK3568 for drone control boards presents a superior solution.
The RK3588 and RK3568 are advanced SoCs tailored for AIoT (Artificial Intelligence of Things) applications. These chips integrate a plethora of functional cores, making them robust choices for drone development.
RK3588 Features: It boasts a CPU with a quad-core A76 and quad-core A55 architecture, reaching clock speeds up to 2.4GHz. Its GPU, the G610 MP4, is one of the most advanced ARM graphics processors available. Additionally, the RK3588 includes dual 8K VPUs for video encoding/decoding and a 48M ISP for multiple post-processing tasks. With integrated Cortex-M0 MCUs and a tri-core NPU delivering 6TOPS@int8 of computing power, the RK3588 excels in general and AI-specific computing tasks.
RK3568 Features: While similar in functionality to the RK3588, the RK3568 offers slightly lower performance. It includes a quad-core A55 CPU, a G52 GPU, a 1TOPS NPU, an 8M ISP, and supports 4K decoding and 1080P encoding.
Both SoCs surpass many modular drone systems in processing power, making them ideal for developing highly autonomous drones. These drones can run AI algorithms to adjust to real-time conditions without human intervention, a critical trend for the future, especially for tasks requiring collaborative drone operations.
