FlyMaple inertial navigation is an open source control panel.
It can be used such as the need attitude and compass and barometer project Quadcopter, unmanned fixed-wing aircraft, two self-balancing, three-axis electronic compass, altimeter and other climbers.
FlyMaple based maple open programming architecture, many fans can join secondary development.
32-bit processors up to 90MIPS of operation to meet the complex computing needs.

• Use STM32RET6 ARM 32-bit processor, FLASH ROM 512K, RAM 64K, frequency 72MHZ.
• Integrated ITG3205 3-axis gyroscope, integrated ADXL345 3-axis accelerometer, 3-axis electronic compass integrated HMC5883, integrated BMP085 high-precision barometric altimeter.
• 3PIN with 6-channel GPIO structure leads can be easily controlled 6-way power adjustment or servos, with 8 3PIN structure GPIO leads can be used to capture the output of the receiver RC model aircraft.
• With external expansion port, external GPS module, with extended I2C interface, for example, can be connected to measure the height of the ultrasonic module, with external expansion port can be connected to the wireless communication module.
• USB-powered with an external power supply automatically switches the input voltage: When connected to the USB without external power supply or external 7V ~ 12V DC input, output voltage: 5V DC output and 3.3V DC output and external power output directly.

Use STM32RET6 ARM 32-bit processor, FLASH ROM 512K, RAM 64K, frequency 72MHZ.Haweier
