Building a DIY Mini FPV Drone with a Custom ESP32 Controller
The world of First Person View (FPV) drones is usually dominated by expensive radio protocols like ELRS or Crossfire. However, for hobbyists looking to learn the ropes of electronics and programming, building a drone from scratch using the ESP32 microcontroller is an incredibly rewarding project. The ESP32 provides built-in Wi-Fi and Bluetooth, but more importantly, it supports ESP-NOW—a low-latency connection protocol perfect for remote control applications. In this guide, we will walk through the steps to build a mini brushed FPV drone and a custom-built handheld controller, both powered by the ESP32. Why Use ESP32 for a Drone? The ESP32 is a powerhouse for DIY projects. Unlike traditional Arduino boards, it features a dual-core processor, high clock speeds, and integrated wireless communication. By using the ESP-NOW protocol, we can achieve significantly lower latency than standard Wi-Fi, making it fast enough to pilot a small drone in real-time. Additionally, the ESP32 is a...
