There are already many cheap ESP32 drones on AliExpress, or you can even make an ESP32 DIY drone for about $12, but ...

I added the ESP32 as a New Device, entered the SSID and Password for my home network, and saved the Encryption Key to my Vaultwarden container, in case I need it later.

Open up the schematic for what is in the ESP32 MODULE. There’s more than the IC in there. Decoupling caps are always a good idea since you are dealing with a radio that will have peak transmissions.

The ESP32 cam itself is mounted on the “head” on the robot for a good field of view. ... Circuit diagrams and code are available for anyone wanting to perhaps make a similar project.
