Install SourceTX your way.

Choose a standalone companion for guided maintenance, or try the browser alpha when you want a direct desktop USB workflow. Both paths use the same signed SourceTX release feed.

STANDALONE APPS01

Windows or Android.

Use the supported desktop or phone companion for guided installation, signed updates, and model backup or restore.

WEB BROWSER / ALPHA02

Install and configure from your browser.

Use Chrome or Edge over HTTPS to connect directly to the official USB target and verify release data locally.

a safer first run

Start with the vehicle restrained.

The shortest path to a good first drive is a careful one. SourceTX gives you the checkpoints; the builder still owns the hardware and the load.

Open the installation guide
  1. 01
    Confirm the target.

    Match the ESP32-S3, flash, PSRAM, display, touch controller, pins, module, and antenna to the reference.

  2. 02
    Install through a companion.

    Use the signed factory flow for a blank board, or the signed OTA path for a compatible running unit.

  3. 03
    Calibrate with drive power off.

    Center controls, verify direction and endpoints, select the intended model, and configure receiver failsafe.

  4. 04
    Watch the return path.

    Keep throttle hold available and treat link loss, stale telemetry, or unexpected response as a stop condition.

Bring SourceTX into the next surface platform.

We welcome serious conversations around reference hardware, radio-module integration, companion distribution, testing, and vehicle-specific control systems. Start with a clear brief: target hardware, intended market, load, RF module, and support model.
