DroneBridge turns an ESP32 into a telemetry radio for ArduPilot, PX4, INAV and Betaflight. Wire it to the flight controller's serial port and it carries MAVLink, MSP or LTM over Wi-Fi or long range ESP-NOW to QGroundControl, Mission Planner or your phone. Settings live on a web page served by the board. Original project by DroneBridge on GitHub, Apache-2.0. Chipnik hosts the release binaries unchanged so you can flash them from the browser.
Connect the board's TX and RX pins to a free UART on the flight controller and power it from 5 V. The pins and the link mode are set on the web page at 192.168.2.1 after the first start.
The file system part holds that web page.
Firmware files come from the v2.4.1 release.
