Welcome to our complete guide on how to choose the best drone design board. If you are interested in building your own drone or working on a drone project, selecting the right PCB (Printed Circuit Board) design is crucial for the success of your project. In this guide, we will walk you through the important factors to consider when choosing a drone design board and provide you with valuable tips to help you make an informed decision.

What is a Drone PCB Design?

A Drone PCB (Printed Circuit Board) design refers to the process of creating and designing the circuit board that serves as the brain of a drone. It is an essential component that houses various electronic components and connections, allowing the drone to function properly.

Characteristics of Drone PCB Design

When designing a PCB for a drone, there are several key characteristics that need to be considered:

  1. Firmware: The firmware is the software that controls the operations of the drone. The PCB design should include the necessary components and connections to support the firmware.
  2. Layout: The layout of the PCB should be optimized for the specific drone model and its intended use. It should take into account factors such as size, weight, and the placement of components to ensure efficient and reliable performance.
  3. Blackbox: Some advanced drone PCB designs include a blackbox feature, which is essentially a data recorder that captures flight data and can be analyzed for troubleshooting or performance improvement purposes.

Types of Drone PCB Designs

There are different types of PCB designs used in drones, each serving a specific purpose:

  1. Drone Power Production Board: This type of PCB is responsible for managing the power distribution and regulation within the drone. It includes components such as voltage regulators, power connectors, and battery management systems.
  2. Drone Controller Board: The controller board is the main processing unit of the drone. It houses the microcontroller or microprocessor, sensors, and other components necessary for flight control and navigation.
  3. Ardupilot: Ardupilot is an open-source autopilot system used in many drones. It has its own specific PCB design, which integrates the necessary components for autonomous flight and mission planning.

Each type of PCB design plays a crucial role in the overall functionality and performance of the drone. They work together to ensure stable flight, accurate navigation, and reliable control.

How do you Make Drone PCB Design?

You’ll need a special film, a pointer, and something called UltraViolet Solder Mask.

First, you’ll need to cut the film a bit bigger than your circuit, but not too big. You want some extra space for later. Stick the film onto the circuit board using tape, pressing down firmly.

Now, mark the spots on the circuit board where you don’t want the solder mask with a marker. This helps when you’re soldering later.

Next, make a copy of those spots onto a new piece of film using a special machine.

Place the new film over the solder paste spots on the board, making sure it lines up perfectly. Put all the connectors in their right places on the film.

Now, expose the board to UV light for about 4 to 5 minutes to set the solder mask.

Once that’s done, carefully remove the film. Clean any dirt with alcohol and a soft cloth. If there’s dried solder paste, gently scrape it off with a knife.

You don’t need to do any more cleaning or apply flux because of some changes in the wires.

Now, solder everything onto the circuit board using a soldering iron. Then, smooth out the solder points with sandpaper to give them a nice finish.

Your drone circuit is ready to go! Just make sure to solder every component to prevent oxidation.


When building your own drone, the controller board is a key component to consider. We’ve covered the basics of drone boards, their features, different types, remote control software, costs, diagrams, and how to design and program a drone board, along with tips for choosing the right one.

Overall, drone controller boards are essential for a smooth and safe UAV flight experience. Selecting the best drone board depends on what you need it to do.
