## STM32F4
!!! info "Continued Support"
Support for existing STM32F4 based radios will continue (i.e. will be supported in EdgeTX v2.12 onwards), but no new handsets will be added.
!!! warning "512KB flash constraint"
Radios marked <span class="flash-warn">⚠ 512KB</span> have only 512KB of flash, which may limit which features can be included in the standard firmware build.
!!! note "SDRAM"
Colour screen radios use an STM32F429 and include 8MB of external SDRAM in addition to the internal SRAM shown below.
