Flashing Firmware


Make sure not to power the radio on without first attaching the antenna! You could damage the radio chip!

Easiest Firmware install options

If you have RAK NRF based devices or a LilyGO T-Echo, the drag and drop firmware installation process is the easiest solution.

For ESP32 based device users (TBEAM, TLORA, Heltec etc.) we recommend using the Meshtastic Flasher application. It does a lot under the hood to prevent you from needing to use the terminal. It also allows you to configure your device.

Manual Firmware Installation

Firmware can be downloaded from the Downloads page. Your initial installation has to happen over USB from your Mac, Windows, or Linux computer.

If you choose to flash the firmware using the manual method, ESP32 based devices and NRF52 based devices have different methods. Select the appropriate one. If you don't know what chipset your device is, take a look at our supported hardware section.
