            > If you are using a STM32 F2 based radio, *stop right now*, this release is not for you! EdgeTX v2.11 is the last release series to support these radios. Check [this list](https://hackmd.io/@edgetx/B12oQyQKye) if you are unsure if this affects you. Because of this, EdgeTX v2.11 will continue to be supported alongside 2.12, 3.0, etc., with a focus on bug fixes.

-            > Radios based on STM32H7 MCUs update differently to older radios. Do **not** use the "Flash via USB" option in EdgeTX Buddy with them (yet). To update radios such as the Flysky PA01 & ST16, Jumper T15 Pro, RM TX15, RM GX15 and RM TX16S MK3, please follow the instructions in the [EdgeTX Manual](https://manual.edgetx.org/installing-and-updating-edgetx/updating-your-stm32h7-radio).

+Hardware notes (vs RadioMaster TX15, on which the display/LTDC wiring is based):
+ - No I2C IO expander: switches, keys and trims are wired directly to GPIO
+   (see boards/hw_defs/h17.json which is the source of truth for those).
+ - Parallel RGB (LTDC) panel, no MCU-side SPI configuration bus.
+ - Analog audio through DAC1 + external amplifier with hardware mute.
