A drone board has several sensors for perceiving the motion of the device and the handler commands. With this information, it can regulate the speed of the engines and make the drone move appropriately. These are the main features of a drone board.


You can fix various firmware on your drone boards to achieve different purposes and specializations. For instance, iNav is manufactured with GPS applications in mind, while KISS is suitable for racing. Section four of this guide contains a detailed discussion of the various drone board firmware for use.


The Drone board processor is also known as a microcontroller unit (MCU). It will help if you have it to keep your firmware codes and solve complicated calculations. There are five primary types of drone board processors based on the processing power and memory size: F1, F3, F4, F7, and H7.


UART is an abbreviation for Universal Asynchronous Receiver/Transmitter. The hardware serial interface enables designers to link external parts, like a Telemetry, to the drone boards. It is advantageous to have more than one UART port, but your drone board’s design dictates this.


The drone board layout houses the solder pads. Many people ignore the significance of the design, but the drone boards with pads positioned on the edges are more potent than those containing all the pillows at one point.


You need a BlackBox to tune and troubleshoot your drone.

What you need to build a drone?

Technology has simplified the process of making drones like never before. Currently, there are drone kits on offer that you can acquire from your local shop. Whether you want to build from an assembled drone kit or scratch, these are the tools you need to navigate through the drone building process smoothly.

The Frame

Your drone requires a frame to host all the other parts. You have two options concerning a frame for your UAV. You can create it from scratch or purchase it from your nearest store. To learn more about the different frames, check out this article about the best drone frames.

Building a frame from scratch is not so challenging, but you have to learn some engineering basics and be aware of the right materials to use. For example, you can use a light metal, plastic, or wood slats. If you settle for a wooded frame, use a wood board that is 2.5 cm thick.


Your drone uses motors to rotate the propellers. A quadcopter uses four motors, while an octocopter needs eight motors to function. It is recommendable to use brushless motors as they have lighter batteries. For DIY drone fans who lack comprehensive engineering knowledge, buy your motors from a trusted dealer.

Since motors will define how your drone will function, choose the appropriate motors for your product’s success. It would be best if you consider the length they cover, RPM, and power consumption.

Electronic Speed Controls (ESC)

An ESC is an electronic circuit that modifies a motor’s speed and direction. It can also act as a dynamic brake. An electronic speed controller purposely converts DC battery power into three-phase AC to power brushless motors. Therefore, if you use brushless motors, you require an ESC, but you do not need them when working with brushed motors.

You should connect your electronic speed controllers directly to the power source using a wiring harness or power distribution board. They have a built-in battery eliminator circuit (BEC) that facilitates other parts’ powering, such as the flight control board and radio receiver.


You need the 3.5 mm connectors to hold the motors and ESCs, and the 4.5 mm connectors for your power distribution board.

Flight Controller

The flight control board acts as the ‘brain’ of a drone. It comprises sensors, like gyroscopes and accelerometers, which determine the speed of rotation of the motors. Flight controls come in all sizes and shapes.
