While the built-in image transmission Mini-OSD brushes into default. The special Rush-OSD can be used to cooperate with the flight control to achieve the return of flight parameters.
Fourthly: The independent integrated system uses a highly integrated system to make players only need to solder motor solid wiring when they connect wires. While the circuit board and the fuselage apply shock isolation technique. It can help flight control shock absorption. What’s more, it can protect the circuit when the aircraft explodes. The battery plug is XT60 standard plug and uses the protection mechanisms of plug and the circuit board. Even if the user use a larger force to plug or pluck the power plug, it would not cause too much damage to the circuit board .
Fifthly: The use of open source flight control and open source power ESC technology, players can play the hardware to the fullest on their own. Focusing on the introduction of the hardware configuration of the integrated circuit chip:
- The main controller:
STM32F103CBT6 is ARM 32 bit Cortex-M3 CPU. The maximum operating frequency is 72MHz. 1.25DMIPS / MHz, 128KB FLASH, and 20KB SRAM. The algorithm is Single-cycle multiply and hardware divide. The main controller has nine peripheral interfaces of USB, USART, SPI, I2 C and so on. It has much more computing power than eight of ATMEL AVR so that it can achieve more and more complex software algorithms. And it has more expansibility. The debug mode: Serial Debug (SWD) and JTAG interface. You can also use the built-in BOOTLOAD to achieve download by serial port.
- MPU6050 MEMS three-axis accelerometer + three-axis gyroscope
It is the main attitude sensor. The MPU6050 chip of InvenSense company integrates a three-axis accelerometer and three-axis gyroscope. It not only eliminates the alignment between accelerometers and gyroscopeserror which is caused when we solder circuit board, but also when aerocraft is subjected to large vibration, we can use programme to set appropriate frequency of the low-pass filter to filter out high-frequency vibration because of its built-in digital programmable low-pass filter. It is a very effective way to reduce the impact that four-axis fuselage vibration towards to the data of gyroscope. Gyroscope maximum range:. ± 2000 ° / sec. Accelerometer: ± 16G.
- HMC5883L Three-axis magnetometer electronic compass
Honeywell HMC5883L is a surface mount highly integrated module, and it has a weak magnetic sensor chip with a digital interface. It puts into use low-cost compass and the magnetic detection field. HMC5883L contains the most advanced high-resolution HMC118X series magnetoresistive sensor, and attaches with Honeywell’s patented integrated circuit (includes an amplifier, automatic degaussing drives, bias calibration, precision control). It allows the compass in 1 °~ 2 °of 12 modulus converter. It is mainly used for measuring the strength of Earth’s magnetic field at MWC flight control to calibrate the aircraft heading. Maximum range: ± 8 Guass, resolution: 2 m Gauss. It should not have a relatively large magnetic materials or large current lines around the sensor. Try to keep relatively far distance from the buzzer and iron objects .
- MS5611-high precision barometer
MS5611 pressure sensor is a new generation of high-resolution pressure sensor by MEAS (Switzerland) releases which combines SPI and I²C bus interface. The resolution can reach to 10cm. The sensor module includes a high linearity pressure sensor and an ultra-low-power 24-bit Σ ADC (factory calibration coefficients). MS5611 provides a precise 24-bit digital pressure, temperature values and different operating modes. It can improve the conversion speed and optimize current consumption. High-resolution temperature output can achieve altimeter / thermometer function without additional sensors. It can be connected to almost any micro-controller. Communication protocol is simple and does not need to stockpile programme in the internal device. MS5611 pressure sensor has only small size of 5.0 mm × 3.0 mm × 1.0 cm. It can be integrated in a mobile device. The MEMS sensor employs leading technology and benefits from MEAS (Switzerland) more than ten years of mature design and high-volume manufacturing experience. It ensures that the product has high stability and very low pressure signal lag. The main role of the MEMS sensor in MWC flight control is to fix height.
