The autonomy of a drone is influenced not only by the engine or camera but also by the quality of the onboard computing module. It is responsible for data processing, navigation, and payload control. If a mistake is made at the selection stage, the device may fail at the most critical moment. That is why it is essential to evaluate the technical specifications of the equipment in advance and determine the critically important functions.
Main criteria for selecting a board
When choosing a microcomputer, frequency plays an important but not a key role. In fact, the system's efficiency depends on a whole range of parameters. Before purchasing, it is worth paying attention to the following:
- processor performance — the number of cores and clock frequency determine the speed of telemetry and video stream processing;
- RAM size — this affects how complex algorithms the board can execute without external servers;
- expansion interfaces — PCIe, MIPI, and USB 3.0 are necessary for connecting drives, cameras, and sensors;
- power requirements — determines the stability of operation during peak loads;
- thermal regime — the ability to maintain frequency without throttling affects the speed and accuracy of computational operations.
If even one characteristic is underestimated, it will nullify all other advantages. For example, a super-powerful processor without proper cooling loses frequency during active operation.
Performance and memory for specific tasks
Optimal microcomputers for drones can be selected on the website of the online store Zelen Store. Technical consultants will help choose a configuration for specific operating conditions and loads.
For basic ground stations and telemetry collection, 4 GB of RAM is sufficient. For local execution of neural networks or 3D mapping, top versions with 16 GB of onboard memory are required. There is a high demand for Raspberry Pi 5 onboard computers, which operate on the Broadcom BCM2712 processor. Additionally, they support ArduPilot, PX4, and ROS 2, which are standard for UAV operations.
Note that electronics are extremely sensitive to power supply. Modern systems connect according to the 5V/5A standard, which reduces the risk of overload during high activity moments. Proper thermal regime and active cooling also play an important role — this affects how accurate the chip's computation results will be.
The choice of a microcontroller for UAVs requires a careful assessment of all technical parameters. There is no universal solution: the configuration must match the specific task and operating conditions.
