LiteWing DIY ESP32 drone costs about $12 to make

Circuit Digest’s LiteWing is a low-cost DIY drone controlled by an ESP32 module, based on a custom PCB and off-the-shelf parts that costs around 1000 Rupees to make, or $12 at today’s exchange rate. The DIY ESP32 drone was designed as a low-cost alternative to more expensive DIY drones that typically cost close to $70. The result is a WiFi drone that fits in the palm and controlled over WiFi using a smartphone. Interestingly it does not include any 3D printed parts as the PCB forms the chassis of the device. DIY ESP32 drone key features and components Wireless module – ESP32-WROOM-32 for WiFi control using a smartphone. Storage – MicroSD card slot Sensors – MPU6050 IMU for stability control. Propulsion 4x 720 coreless motors 2x 55mm propeller type A(CW) 2x 55mm propeller type B(CCW) USB – 1x USB-C port for charging and programming (via CP2102N) Power Management 1300mAh Li-Ion […]

ESP-FLY DIY Kit is a tiny ESP32-S3-based DIY micro drone kit

ESP-FLY DIY kit is a miniature DIY drone kit based on Seeed Studio’s XIAO ESP32-S3 board that was initially introduced as a DIY project on Instructables by Max Imagination, but is now available as a complete kit for $59.99 on Seeed Studio. It’s certainly not the first ESP32 drone, but the ESP-FLY drone must be the smallest, as the miniature (67 x 67 x 31mm) quadcopter design allows users to store into any pocket or small boxes. It’s mainly designed for STEM education, hobbyist DIY Projects, and indoor flight practice. ESP-FLY drone kit key features and specifications: Main Controller – Seeed Studio XIAO ESP32-S3 board Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller @ 240 MHz System Memory – 512KB SRAM, 8MB PSRAM Wireless – Wi-Fi 4 & Bluetooth 5.0 dual-mode (Classic + BLE) connectivity Storage – 8MB SPI flash Antenna – External u.FL antenna USB […]

pyDrone – An ESP32-S3 drone running MicroPython firmware

There are already many cheap ESP32 drones on AliExpress, or you can even make an ESP32 DIY drone for about $12, but 01Studio’s pyDrone is a little different as it’s based on an ESP32-S3-WROOM-1 module and runs MicroPython firmware instead of the ESP32-Drone firmware. The pyDrone can be controlled over WiFi or Bluetooth using the pyController gamepad, also based on the same ESP32-S3 module. Another advantage of the pyDrone is that it comes with a connector for the OV2640 camera module that’s often missing in other low-cost ESP32 drones. pyDrone specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – ESP32-S3N8R8 CPU – Dual-core Tensilica LX7 up to 240 MHz RAM – 512KB SRAM, up to 8MB PSRAM Storage – 8MB flash Wireless – WiFi 4 and Bluetooth LE 5 Antenna – PCB antenna Motors – 4x 716 hollow cup motors Blades – 46mm propeller blades Flight range WiFi – 120 meters Bluetooth […]

Map Remote ID-enabled drones with ESP32-C3/S3 and Meshtastic LoRa modules

Colonel Panic’s Mesh Mapper is a project designed to map drones emitting the FAA’s Remote ID over WiFi or Bluetooth with location, altitude, pilot position, and identification data. This project utilizes an ESP32-C3 or ESP32-S3 to capture Remote ID transmissions within range, and then feeds the data into a Python Flask web application part of Mesh Mapper that provides real-time visualization and logging. Meshtastic allows multiple detection nodes to share information across a mesh network, so several ESP32 nodes can be deployed in an area and be alerted when drones fly within your property or neighborhood. While you could use your own ESP32-C3/S3 board and Meshtastic hardware for this project, Colonel Panic designed a breakout board for XIAO ESP32C3 or ESP32S3 WiFi & Bluetooth module and Heltec LoRa 32 V3 connected over serial to make things easier. Something like the XIAO ESP32S3 for Meshtastic & LoRa devkit might also do, […]

M5Stamp Fly ESP32-S3 WiFi drone is controlled by the M5Atom WiFi joystick controller using ESPNOW

M5Stack M5Stamp Fly is a tiny ESP32-S3 WiFi drone based on the company’s M5Stamp S3 WiFi 4 and BLE IoT module, equipped with four motors and several sensors. and controllable, the M5Atom WiFi joystick controller is also based on ESP32-S3 WiSoC. We have recently seen some tiny ESP32 or ESP8266 WiFi drones with a low-cost ESP32 DIY drone and the PiWings 2.0 drone, but the M5Stamp Fly is more advanced with a total of six sensors, including a barometer, two time-of-flight distance sensors, a 6-axis IMU, a 3-axis magnetometer, and an optical flow detection sensor, plus two Grove connectors for additional sensors or modules. M5Stamp Fly (K138) specifications: Main controller – M5Stamp S3 module WiSoC – Espressif Systems ESP32-S3FN8 dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz, RISC-V ULP co-processor, 512KB SRAM, 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 BLE + Mesh, 8MB flash Connectivity 2.4 GHz […]
