1 # Board - Seriously Pro SP Racing H7 EXTREME
3 The SPRacingH7EXTREME flight controller features a 400Mhz H7 CPU that runs twice as fast as the previous generation F7 boards.
4 A fast control-loop is what you need for perfect flight performance, the H7 at 400Mhz gives you all the processing power you need.
6 The SPRacingH7EXTREME has integrated OSD (on-screen-display) and PDB (power distribution board) and features all the latest technologies available.

18 The SPRacingH7EXTREME FC is the first STM32H750 based FC to ship with Betaflight. It is unique among Cleanflight/Betaflight based FCs as it is the first
19 to use the External Storage (EXST) build system which allows a bootloader to load the flight-controller firmware from either external flash or via SD card.
21 See the EXST documentation for more details on the EXST system.
25 The SPRacingH7EXTREME can be stand-alone or be turned into a stack that allows fitting of TBS Unify Pro or FX578-2-SPI VTX modules.
