Attention

ExpressLRS 3.5.x will be the last version to support STM32-based hardware. This includes the Happymodel PP, ES915 Tx and Rx, early NamimnoRC Flash and Voyager, FrSky R9, SIYI and ImmersionRC hardware.

The STM32 platform's limited compute resources and feature gaps (WiFi, Bluetooth, Backpacks) made for an inferior version of ExpressLRS that necessitated disproportionate maintenance burden for the Dev Team.

  8. On your radio, open the System Menu.

    • On newer radios, you can press the SYS key to open the System Menu
    • On older radios, or radios that only have a menu key, long-press the Menu key to open the System Menu

  9. Using the Page key/s, navigate to the SD-HC Card page, scroll-down and open the FIRMWARE folder where you can find the firmware.elrs file.

  10. Highlight the file and press-hold the Enter button and select "Flash External ELRS". Wait for the firmware to be written.
