Pixhawk 2.4.6 Description:

- SD card base adopts deadlock function. The SD card will not be easily taken out unless you press the SIM.
- The front jacks all adopt imported gilded needles, which have better contact resistance, and are more stable and reliable.
- NEC original tantalum capacitors are added to the back compass and main power supply, making each sensor have a stable power supply and a lower possibility of aircraft crashing.
- The same matte black gold plate as the original version, high quality.
- Pixhawk integrated the newest 32-bit chip technology and sensor technology, eliminating the dilemma of having only an 8-bit CPU in APM, and CPU occupancy being too high.

Features:
- With external LED - Dual-size full-angle LED
- Advanced 32-bit ARM Cortex-M4 high-performance processor, can operate NuttX RTOS real-time operating system.
- 14 PWM/Servo Outputs
- Bus interfaces (UART, I2C, SPI, CAN)
- Integrated backup power and loss-of-efficacy controller; the main controller loss of efficacy can safely alter to backup control.
- Providing automatic and manual modes.
- Providing redundant power supply input and failover.
- Multicolor LED light.
- Providing multiple sound buzzer interfaces.
- Micro SD records flying data.

Hardware parameters

Processor:
- 32-bit 2M flash memory STM32F427 Cortex-M4, with hardware floating-point processing unit.
- Main frequency: 168MHz, 256K RAM.
- 32-bit STM32F103 backup processor.

Sensor:
- L3GD20 3-axis digital 16-bit gyroscope.
- LSM303D 3-axis 14-bit accelerometer/magnetometer.
- MPU6000 6-axis accelerometer/magnetometer.
- MS5611 high-precision barometer.

Interface:
- 5 UARTs, one compatible with high voltage, two have hardware flow control.
- Two CAN.
- Spektrum DSM/DSM2/DSM-X satellite receiver compatible input.
- Futaba S.BUS compatible input and output.
- PPM signal input.
- RSSI (PWM or voltage) output.
- I2C.
- SPI.
- 3.3 and 6.6 V ADC input.
- External Micro USB interface.

NEO-M8N GPS Specification:
- NEO-M8N has low consumption, high precision (approximately 0.6m), most are about 0.9m according to tests.
- Compared to NEO-7N (1.4-1.6m), the precision has been greatly improved, and it supports GPS/QZSS L1 C/A, GLONASS L1OF, BeiDou B1.
This is not an ordinary cheap GPS module. It is worth $60.
