Processors: Utilizes Atmel's ATMEGA2560 for main processing and ATMEGA32U-2 for USB functions. Sensors: Includes a 3-axis gyroscope and accelerometer (MPU-6000), along with a high-performance barometer (MS5611-01BA03). Compass (Magnetometer): The APM 2.8 board gives the user the option to use either a built-in compass or an external one via a jumper cap. For optimal performance in multi-copters, an external GPS/Compass module mounted away from motor interference is often recommended. Input Voltage: Operates on a 12-16 VDC input (can handle up to 16V with the upgraded power supply design). Data Logging: Features an onboard 4 MegaByte Dataflash chip for automatic flight data logging. Connectivity: Includes ports for GPS, I2C, power module input, telemetry radio, and OSD (On-Screen Display). Compatibility: Arduino-compatible and configurable using the free, downloadable Mission Planner software
