If you are looking for more computing power with your Pixhawk 2.1 autopilot, then this Intel Edison version (Intel Edison compute module sold separately) of the pixhawk 2.1 system will be ideal for you.  With its dual core atom processor the Edison compute module will have loads of processing power for whatever application you decide to use this autopilot for, be it computer vision tasks, or advanced flight algorithms.  At the heart of the pixhawk 2 is the cube, which is an isolated and damped high precision, redundant IMU unit to ensure the flight calculations are accurate, and reliable.  The intel Edison compute module simply plugs into this pixhawk 2.1 carrier board and provides all of the I/O functionality of the standard Pixhawk 2 carrier board.

Furthermore this kit includes the precision Here GNSS GPS module with large ground plane for accurate and interference free GPS positioning.  So you just need to add your own Intel Edison compute module to use this autopilot.

EMI FILTERING

EMI filtering is provided at key points in the system using high-insertion-loss passthrough filters. These filters are paired with TVS diodes at the peripheral connectors to suppress power transients. Reverse polarity protection is provided at each of the power inputs. USB signals are filtered and terminated with a combined termination/TVS array. Most digital peripheral signals (all PWM outputs, serial ports, I2C port) are driven using ESD-enhanced buffers and feature series blocking resistors to reduce the risk of damage due to transients or accidental misconnections.

BATTERY BACKUP

Both the FMU and IO microcontrollers feature battery-backed real-time clocks and SRAM. The on-board backup battery has capacity sufficient for the intended use of the clock and SRAM, which is to provide storage to permit orderly recovery from unintended power loss or other causes of in-air restarts. The capacitors can also be recharged from the FMU 3.3V rail, however this will only function in the event of software existing to support this feature.

VOLTAGE, CURRENT AND FAULT SENSING

The battery voltage and current reported by both bricks can be measured by the FMU. In addition, the 5V unregulated supply rail can be measured (to detect brownout conditions). I/O can measure the servo power rail voltage. Over-current conditions on the peripheral power ports can be detected by the FMU. Hardware lock-out prevents damage due to persistent short-circuits on these ports. The lockout can be reset by FMU software.

The under/over voltage supervisor for FMU provides an output that is used to hold FMU in reset during brown-out events.
