PX4IO is the Input/Output module for fixed-wing aircraft and rovers with four relays, servo failsafe and manual override.
The Firmware for PX4IO is managed through the Autopilot and does not require any user steps for upgrades / setup. To set the system up, follow the first_steps page.
Any airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. More details are available on the platforms page.
The following connectors can be used to make connections between PX4IO and other devices. Note that indicated voltages are ABSOLUTE MAXIMUM RATINGS. Connect only 5V BECs designed to be potentially back-powered to the 5V rail. If powering through the BAT connector (absolutely recommended, its the connector for which a plug with one red and one black cable ships), a 2 cell LiPo, 3 cell LiFePo or 6 cell NiMH / NiCD battery (all cells in series) is in general required to ensure safe operation.
Spacers to stack PX4 boards, are included as part of the 3D Robotics delivery.
These jumper wires are suitable for the housings below.
The PX4 system has a stacking concept for combining the PX4FMU autopilot-on-module with a carrier board that interfaces to the airframe and provides a stable 5V power supply. This concept allows to have a very customized solution for each type of airframe and still share the same autopilot module. The image on the left shows PX4FMU Autopilot / Flight Management Unit and PX4IO Airplane/Rover Servo and I/O Module stacked as complete fixed-wing/car/boat solution.
