SP Racing H7 ZERO

The Seriously Pro 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.

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.
