Introduction
FMUv4-PRO takes input from all of the Pixhawk stakeholders; end users, developers, researchers and manufacturing partners. Goals for this iteration of the platform are:
    An integrated, single-board flight controller for space constrained applications
    A modular multi-board flight controller for professional applications
    Sufficient I/O for most applications without expansion.
    Improved ease-of-use.
    Improved sensor performance
    Improved microcontroller resources (384 KB RAM, 2 MB flash).
    Increased reliability and reduced integration complexity.
    Reduced BoM and manufacturing costs.
Key design points:
    All-in-one design with integrated FMU and optional IO and lots of I/O ports.
    Improved manufacturability, designed for simpler mounting and case design.
    Separate power supplies for FMU and IO (see power architecture section).
    Onboard battery backup for FMU and IO SRAM / RTC.
    Integration with two standard power bricks.
Technology upgrades:
    Microcontroller upgrade to STM32F469; flash increases from 1MiB to 2MiB, RAM increases from 256KiB to 384KiB, more peripheral ports.
    ICM-20602, MPU9K integrated gyro / accelerometer / magnetometers.
    LIS3MDL compass (HMC5983 is now obsolete).
    Sensors connected via two SPI buses (one high rate and one low-noise bus)
    Two I2C buses
    Two CAN buses
    Voltage / battery readings from two power modules
    FrSky Inverter
    JST GH user-friendly connectors
