About the Minicopter PCB

Minicopter is an open source ESP32 PCB design by darshg321, published on GitHub. It is a 2-layer board measuring 136.1 × 135.4 mm, with 57 components from 27 distinct parts.

Its main chip is the ESP32-C3-WROOM-02, from the ESP32 family. Other key parts include the SPX3819M5-L-3-3, TP4056-42-ESOP8, GY-87_MODULE and USBLC6-2P6. By type, the board carries 18 resistors, 12 capacitors, 10 diodes, 6 connectors, 5 ICs and 4 transformers.

It belongs with the robotics & motion, power & battery and iot & wireless designs in this gallery.

From the project

Compact and precise ESP-32 based drone capable of autonomous pathing, built from scratch

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…

Minicopter: common questions

What microcontroller does the Minicopter use?

The Minicopter is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Minicopter PCB?

The Minicopter measures 136.1 × 135.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Minicopter?

57 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Minicopter design files?

From the darshg321/Minicopter repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Minicopter design in my own project?

The repository has no license, so all rights stay with darshg321. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Minicopter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
