This article details the creation of a low-cost drone using ESP32, a microcontroller unit with Wi-Fi connectivity, for less than Rs.1000. The project demonstrates clever use of the PCB as the drone frame, reduction of extra components like transmitters and receivers due to ESP32’s features, and the importance of calibration for proper operation. A detailed walkthrough of the construction process, including circuit diagrams and programming instructions, is provided for enthusiasts to replicate the project.
Main Points
Drone uses ESP 32 as flight controller
The drone uses ESP 32 as its flight controller, which can be controlled from a mobile phone using Wi-Fi, showcasing an innovative approach to reducing costs and complexity in drone construction.
PCB itself used as drone frame
For constructing the drone, no separate frame was used; instead, the PCB itself acted as the frame, signifying a clever utilization of components for multipurposes.
Android app connects to drone via Wi-Fi
A particular Android app connects to the drone via Wi-Fi, demonstrating the integration of smartphone technology with remote-controlled devices.
Importance of calibration for operation
Initial calibration through the mobile application is crucial for correct drone operation, highlighting the importance of software adjustments in hardware performance.
Insights
The project goal was to create a cost-effective drone for around 1,000 rupees using ESP32 as the flight controller.
with its electronic speed controller the BLC motor the flight controller the battery the transmitter and receiver a simple drone like this would cost somewhere around 6,000 Rupees to build one the idea of this project is to build a lowcost drone like this one which has cost somewhere around 1,000 rupees to build
ESP32's built-in Wi-Fi feature eliminates the need for a separate transmitter and receiver, making the project more affordable and simpler.
there is no transmitter or receiver in our drone that is because the esp32 itself has Wi-Fi connectivity
Detailed guidance including circuit diagrams and programming instructions is provided to assist others in replicating the project.
if you already know how to build a PCB you can directly use this circuit diagram and build it on your own or you can directly head over to our website link for the same can be found at the description and here you can find all the details including the total cost for building the project the circuit diagram the 3D model the uh procedure on how to upload the esp32 firmware onto a drone
