PX4 Hardware
The PX4 project designed a series of hardware modules used to guide vehicles in both human-assisted and fully-autonomous operation. The currently available modules include the main autopilot (called FMU β Flight Management Unit), platform-specific carrier (called IO β input/output) modules that output servo signals and motor commands and an optical flow camera module.
All modules are CC-by-SA open hardware designs. Notes on commercial hardware offerings and open hardware
Autopilot Modules
PIXRACER X1 Autopilot
Pixracer X1 is the latest addition to the PX4 hardware family. It is radically reduced for FPV racing quads and planes and features only the main processor.
- 168 MHz Cortex M4F CPU (256 KB RAM, 2 MB Flash)
- Sensors: New 3D ACC / Gyro / MAG / Baro
- microSD slot, 3 UARTs, 1 CAN, 1 I2C, ADC
PIXHAWK 1 Autopilot
PIXHAWK is the all-in-one unit, combining FMU and IO into a single package. With hardware floating point unit and SIMD.
- 168 MHz Cortex M4F CPU (256 KB RAM, 2 MB Flash)
- Sensors: 3D ACC / Gyro / MAG / Baro
- Integrated backup, override and failsafe processor with mixing
- microSD slot, 5 UARTs, CAN, I2C, SPI, ADC, etc
PX4FMU Autopilot (FMUv1)
PX4FMU is the core module, the Flight Management Unit. With hardware floating point unit and SIMD.
- 168 MHz Cortex M4F CPU (196 KB/1 MB)
- Sensors: 3D ACC / Gyro / MAG / Baro
- microSD slot, 50 pins of connectivity
PX4FLOW Smart Camera
PX4Flow is an optical flow camera. Provides optical flow at 250 Hz. Unlike mouse sensors it works indoors without illumination LED.
- 168 MHz Cortex M4F CPU (196 KB RAM)
- 752×480 MT9V034 imager, 3D Gyro
- 16 mm M12 lens, microSD slot
