1,Pixhawk/PPZ/MK/MWC/PPM Encoder PPM built-in IMU independent seismic design, the first generation of Pixraptor using silica gel platform, the second generation of Pixraptor reference design of Pixhawk V3, with foam damping system, using a supporting IMU module, IMU module and plate clip gauge filter sponge. In addition, according to feedback, the new version has also been referred to the V3 circuit to increase the IMU sensor power supply system pressure relief, to ensure that the LSM303D repeat power on time reset.

2, all the DF13 device interface to integrate Pixhawk to the side, the wiring is more beautiful and convenient, all DF13 interface devices are compatible with the original Pixhawk device interface definitions are exactly the same, which only omits the DF13 external USB interface function, this function can achieve through a micro USB male and female extension line, the original DF13 USB interface is only a parallel in a branch of the internal USB interface.

3, the LED indicating lamp post, because the original Pixhawk LED status indicator is a top emitting display, make our normal flight or flight control is installed in the mezzanine, I cannot see the light of LED, must use an external LED display module. Therefore, we will led module board is transferred to the rear side, so that no external LED module can also see the flight control LED state, the rear side of the LED settings are more in line with conventional people took off in the rear of the plane is operating the aircraft operating habits. Of course, you can still use the traditional external LED module inserted into the flight control I2C interface external display.

4, to solve the problems in the application of Pixhawk, we build some component parameters, such as the Pixhawk2.4.5 version of Schottky easy to burn the receiver power supply pipe, the Schottky IO system and common receiver power supply diode, while the 2.4.6 version of improved design, using two separate Schottky independent power supply, but the design of each Schottky the maximum current is 500mA, there is still a risk of damage to the flow.
