Pixpilot v2.4.6 (Pixhawk) open-hardware Autopilot Flight Controller

PX4 Pixhawk V2.4.6 32Bits Open Source Flight Controller w/External LED for RC Airplanes

Improvements on V2.4.5

• V2.4.6 PCB board.
• Redeveloped and optimized circuit without changing components.
• Could use Official MissionPlanner, ECLIPSE firmware upgrade.

Features:

• 168 MHz / 252 MIPS Cortex-M4F.
• 14 PWM / Servo outputs (8 with failsafe and manual override, 6 auxiliary, high-power compatible).
• Abundant connectivity options for additional peripherals (UART, I2C, CAN).
• Integrated backup system for in-flight recovery and manual override with dedicated processor and stand-alone power supply (fixed-wing use).
• Backup system integrates mixing, providing consistent autopilot and manual override mixing modes (fixed wing use).
• Redundant power supply inputs and automatic failover.
• External safety switch.
• Multicolor LED main visual indicator.
• High-power, multi-tone piezo audio indicator.
• microSD card for high-rate logging over extended periods of time.

Specifications:

• 32bit STM32F427 Cortex M4 core with FPU.
• 168 MHz.
• 256 KB RAM.
• 2 MB Flash.
• 32 bit STM32F103 failsafe co-processor.

Sensors

• ST Micro L3GD20H 16 bit gyroscope.
• ST Micro LSM303D 14 bit accelerometer / magnetometer.
• MEAS MS5611 barometer.

Interfaces

• 5x UART (serial ports), one high-power capable, 2x with HW flow control.
• 2x CAN (one with internal 3.3V transceiver, one on expansion connector).
• Spektrum DSM / DSM2 / DSM-X® Satellite compatible input.
• Futaba S.BUS® compatible input and output.
• PPM sum signal input.
• RSSI (PWM or voltage) input.
• I2C.
• SPI.
• 3.3 and 6.6V ADC inputs.
• Internal microUSB port and external microUSB port extension .

Power System and Protection

• Ideal diode controller with automatic failover.
• Servo rail high-power (max. 10V) and high-current (10A+) ready.
• All peripheral outputs over-current protected, all inputs ESD protected.
.
• Compare to the old version 2.4.5, the final release 2.4.6 Version is added two components: D1002 and F1002.
• D1002 model: PMEG2005CT.
• This version of flight control can solve the problem of small supply current for receiver, and the flight control system halted caused by overcurrent supply.
