README
README.mdMinicopter
A lightweight ESP-32 based drone capable of autonomous pathing, built for agility. Uses the GY-87 breakout board with a three-axis gyroscope + triaxial accelerometer + three-axis magnetic field + pressure. Charges a LiPo battery with USB-C and can be flashed with firmware. Can be controlled with both pathing commands and bluetooth controls.
I made this project after getting inspiration from a different esp32 drone reel, and thought I could make that too I've additionally always wanted to get into creating a from-scratch hardware project that includes microcontrollers and pcbs, and thought this was the perfect place to start

Questions
How big is the Minicopter PCB?
It measures 136.1 × 135.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minicopter use?
57 parts, built around the ESP32-C3-WROOM-02-H4, SPX3819M5-L-3-3, TP4056-42-ESOP8 and USBLC6-2P6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Minicopter KiCad files?
From the darshg321/Minicopter repository on GitHub, at the commit this page was made from: the board is pcb/Minicopter.kicad_pcb and its schematic pcb/Minicopter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minicopter design in my own project?
Its repository states no licence, so its author keeps all rights: ask darshg321 before reusing the design.
