FMU generations 1-3 were designed as open hardware, while FMU generations 4 and 5 provided only pinout and power supply specifications (schematics were created by individual manufacturers). In order to better ensure compatibility, FMUv6 and onward will return to a complete reference design model.

Reference Design Generations

  • FMUv1: Development board (STM32F407, 128 KB RAM, 1MB flash, ) (no longer supported by PX4)

  • FMUv2: Pixhawk (STM32F427, 168 MHz, 192 KB RAM, 1MB flash, )

  • FMUv3: Pixhawk variants with 2MB flash (3DR Pixhawk 2 (Solo), Hex Pixhawk 2.1, Holybro Pixfalcon, 3DR Pixhawk Mini, STM32F427, 168 MHz, 192 KB RAM, 2 MB flash, )

  • FMUv4: Pixracer (STM32F427, 168 MHz, 192 KB RAM, 2 MB flash,)

  • FMUv4 PRO: Drotek Pixhawk 3 PRO (STM32F467, 168 MHz, 384 KB RAM, 2 MB flash,)

  • FMUv5: final name TBD (STM32F7675, 200 MHz, 512 KB RAM, 2 MB flash,)

  • FMUv6: work in progress, final name TBD, variant 6s (STM32H7, 400 MHz, 2 MB RAM, 2 MB flash) and variant 6i (i.MX RT1050, 600 MHz, 512 KB RAM, external flash)

Question:

Is CUAV Pixhack Nano STM32F427 is suitable for px4?

NOT SURE about that!

It is interesting that in the px4 website, they recommend PIXHACK V3 AUTOPILOT as an altenative of 3DR pixhawk
