Possibly ≤ 1 weekShipping: If stock turns up. Largely gone from US retail; leftover and used units appear on Amazon and eBay. eBay search ↗

Remote control: Same UDP text protocol as the Tello EDU, so djitellopy works from a laptop; the ESP32 add-on can also run its own Arduino or MicroPython code.

Overview

A Tello EDU with an open ESP32 "expansion kit" bolted on top, adding an 8×8 LED matrix, a forward ToF sensor and headers for extra sensors. It adds Wi-Fi router mode for swarms and was DJI's main classroom drone after 2020. The same short flight time and indoor-only limits as the Tello apply.
