DroneBridge for ESP32

A secure & transparent telemetry link with support for WiFi and ESP-NOW.

WiFi Data Link

DroneBridge for ESP32 WiFi connection to GCS

DroneBridge for ESP32 supports traditional WiFi. Run the access point directly on the drones ESP32 or connect to a central access point on the ground.

Long Range ESP-NOW Data Link

DroneBridge for ESP32 ESP-NOW connection to GCS

DroneBridge for ESP32 supports ESP-NOW as a protocol. While similar to WiFi it offers far more range at the cost of some data rate (still 250kbit brutto rate). In contrast to a WiFi setup you will need two ESP32`s running DroneBridge for ESP32. On one the ground and one on every drone.

Features

Up to 150m range using standard WiFi
Up to 1km of range using ESP-NOW or Wi-Fi LR Mode
Fully encrypted in WiFi & ESP-NOW (AES-GCM 256 bit)
High data rates (250kbit ESP-NOW & 11Mbit WiFi mode)
Bidirectional
Support for MAVLink, MSP & LTM telemetry
Support for any payload using transparent option
Supported by QGroundControl, Mission Planner, mwptools, impload etc.
Easy to set up: Power connection + UART connection to flight controller
Fully configurable through an easy-to-use web interface
Parsing modes for reduced packet loss
Ideal for central drone swarm control
Reliable
Low latency
Affordable
Weight: <8 g

A firmware for the popular ESP32 modules from Espressif Systems. Probably the cheapest way to communicate with your drone, UAV, UAS, ground-based vehicle.
It also allows for a fully transparent serial to WiFi pass-through link with variable packet size.
It is ideal for connecting many drones in one single network.

DroneBridge for ESP32 is a telemetry/low data rate-only solution. There is no support for cameras connected to the ESP32 since it does not support video encoding.

Official Hardware

Get started in no time!
Designed according to the DS-009 Pixhawk Connector Standard for easy Plug&Play integration.
Private limited sale. Currently shipping within EU & CH.
For non EU shipping options please contact me via LinkedIn or ebay directly.

You want to build the official board yourself or shipping from the EU is not an option?
While I recommend to just get the ready-made board (cheaper and less of a hassle) you can also get the design & manufacturing files of the official board. E.g. just upload to JLCPCB and assemble yourself.

DroneBridge for ESP32 is free and almost everything is maintained by a single developer! It takes many hundreds of hours to develop, debug and document such software.
Please consider supporting the development by donating any amount or even an Espresso or by ordering the official boards to keep the project running!
