# Board - Seriously Pro SP Racing H7 ZERO
|
||
|
|
||
|
The SPRacingH7ZERO flight controller features a 400Mhz H7 CPU that runs twice as fast as the previous generation F7 boards.
|
||
|
A fast control-loop is what you need for perfect flight performance, the H7 at 400Mhz gives you all the processing power you need.
|
||
|
|
||
|
The SPRacingH7ZERO has integrated OSD (on-screen-display) and single gyro, BMP388 barometer and 2-6SBEC.
|
||
|
|
||
|
Easy to solder! - One entire side of the PCB is dedicated to solder pads.
|
||

|
## Background
|
||
|
|
||
|
The SPRacingH7ZERO FC is the third STM32H750 based FC to ship with Betaflight. Like the SPRacingH7NANO and SPRacingH7EXTREME before it, it too uses
|
||
|
the External Storage (EXST) build system which allows a bootloader to load the flight-controller firmware from external flash.
|
||
|
|
||
|
See the EXST documentation for more details on the EXST system.
|
||
|
|
||
|
## Design Goals
|
||
|
|
||
|
* Easy connection for 2 * 4in1 ESCs for 8 motor outputs.
|
||
|
* No premium hardware features like Microphone, Audio Mixer, Transponder Circuit, Current Sensor or Dual Gyro - See SPRacingH7EXTREME
|
||
|
* Cheaper than SPRacingH7EXTREME.
|
||
|
* No integrated PDB.
|
||
|
* Single sided PCB.
|
||
