ESP32Copter Design

Our design is named ESP32Copter. It is mainly inspired by Espressif's ESP Drone design. We change some parts and add others. The chip crisis is a big challenge! Many parts are not available.

ESP32Copter Bill of Material (BOM)

We are planning to use some other components. The column Ideal Part lists the components we would like to use but which are partly unavailable because of the chip crisis. The column ESP Drone Part is the ESP Drone reference design by Espressif, version 1.2. The column ESP32Copter Part shows the selection of our current design.

The original BOM (xlsx) can be found here
