# SPRacingH7EXTREME (PX4 Edition)

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer (opens new window) for hardware support or compliance issues.

The SPRacingH7EXTREME (opens new window) is a feature packed FC/PDB with DUAL ICM20602 gyros, H7 400/480Mhz(+) CPU, high-precision BMP388 barometer, SD Card socket, current sensor, 8 easily accessible motor outputs, OSD, Microphone, Audio output, and more.

It can be used easily for small to large quads, planes, octocoptors and more advanced frames. It's best used with separate ESCs as it features a built-in power distribution board (PDB). Wiring up a 4in1 ESC is easy too.

There is also a 12 pin stacking connector which provides 4 more motor outputs, SPI and a UART connectivity.
