Their precise control ensures uniform distribution of chemicals, minimizing waste and promoting sustainable agricultural development. Additionally, they can operate in difficult-to-reach terrains, increasing coverage and effectiveness.
Intelligent Drone Control Systems
As an emerging strategic industry, the low-altitude economy imposes higher demands on drones for reliability, endurance, precise control, and intelligence. In the wave of smart drone development, the ARTERY AT32 MCU plays a central role, offering exceptional performance, a rich set of peripheral interfaces, and a comprehensive development ecosystem. It provides strong algorithm support and expanded functionalities for core drone components such as flight controllers, electronic speed controllers (ESCs), and gimbals. Recognized by many drone manufacturers and solution providers, AT32 MCUs are among the most popular choices in the open-source community.
Drone Flight Controller
As the core control unit of drones, the AT32F435 main control chip features a high-performance ARM® Cortex®-M4F core, operating at up to 288MHz, with a maximum capacity of 4032KB Flash and 512KB SRAM. It leads the industry with superior computing power and ultra-fast responsiveness. The AT32F435 enables efficient data interaction and control, seamlessly interfacing with high-resolution image transmission, IMU sensors, GPS modules, and ESCs. During flight, it supports real-time data collection, precise flight control, and intelligent obstacle avoidance, meeting the demands of various applications such as aerial photography, mapping, inspections, and logistics, ensuring each flight mission is stable and reliable.
Drone Electronic Speed Controller (ESC)
The AT32F421, with a CPU frequency of up to 120MHz, 64KB Flash, and 16KB SRAM, delivers fast and efficient algorithm processing at a competitive cost, making it widely used in drone ESC systems. Its high PWM frequency and resolution enable fine torque control, ensuring stable and reliable power output. This allows drones to maintain smooth operation in all flight conditions, achieving precise motor control whether in low-speed hovering or high-speed flight.
With a minimal 4*4mm package size, the AT32F421 perfectly meets the strict size requirements of ESC chips while delivering outstanding control performance in limited space. Additionally, the AT32F421 integrates a high-speed rail-to-rail input/output analog voltage comparator for rapid overcurrent detection and protection, ensuring the safety of motors and driver circuits under extreme flight conditions.
Drone Gimbal
The gimbal is essential for capturing high-quality aerial images, relying on PID control algorithms, Kalman filtering, and quaternion algorithms for stable operation and precise positioning. The AT32F423, featuring an ARM® Cortex®-M4F core, a 150MHz CPU frequency, 256KB Flash, and 48KB SRAM, delivers robust computing power for executing these algorithms. Equipped with a 5.33Msps 12-bit A/D converter, it ensures high-precision signal acquisition, maintaining stability even in complex flight conditions.
The AT32F423 supports synchronized processing of three key tasks: three-axis stabilization, intelligent target tracking, and image stream optimization. Its adaptive PID tuning mechanism dynamically compensates for flight disturbances, while an advanced electronic anti-shake matrix significantly enhances image stability compared to traditional solutions. Whether meeting millimeter-level precision requirements for aerial mapping or enabling rapid scene switching in sports livestreaming, the AT32F423 ensures a smooth and stable gimbal operation.
The integration of drones and the low-altitude economy is opening a new chapter in future airspace. The ARTERY AT32 MCU not only enhances drone performance but also accelerates their widespread adoption across industries. With its high computational efficiency and system stability, it enables drones to achieve higher flight precision, longer operational time, and greater adaptability, providing robust technological support for smart city development and injecting strong momentum into the rapid growth of the low-altitude economy.
