ArduPilot APM 2.8 Flight Controller Board

Description:
This is the new APM 2.8 autopilot module. The sensors are exactly the same as with APM2.6, however this version does not have an onboard compass, which makes this version ideal for use with multicopters and rovers. The APM 2.8 is a complete open source autopilot system and the bestselling technology that won the prestigious 2012 Outback Challenge UAV competition. It allows the user to turn any fixed, rotary wing or multirotor vehicle (even cars and boats) into a fully autonomous vehicle; capable of performing programmed GPS missions with waypoints. Available with top or side connectors. This revision of the board has no onboard compass, which is designed for vehicles (especially multicopters and rovers) where the compass should be placed as far from power and motor sources as possible to avoid magnetic interference. (On fixed wing aircraft it’s often easier to mount APM far enough away from the motors and ESCs to avoid magnetic interference, so this is not as critical, but APM 2.6 gives more flexibility in that positioning and is a good choice for them, too). This is designed to be used with the 3DR uBlox GPS with Compass (see option below), so that the GPS/Compass unit can be mounted further from noise sources than APM itself.

Features:
Input Voltage: 12-16 V.
Processor: ATMEGA2560 and ATMEGA32U-2
Atmel’s ATMEGA2560 and ATMEGA32U-2 chips for processing and USB functions respectively
Dimensions: 70 x 45 x 15 mm
Micro SD card slot: No.

Includes 3-axis gyro, accelerometer, along with a high-performance barometer
Onboard 4 MegaByte Dataflash chip for automatic datalogging
Barometric pressure sensor upgraded to MS5607, from Measurement Specialties.

The interface is changed from 1.0mm 6P SM06B GPS to DF13-4P I2C external compass interface, put DF13- 5P GPS interface with external compass interface.
The I2C interface has been changed to multifunctional MUX interface, users can configure the interface like UARTO, UART2, I2C, OSD, default OSD interface
2.8 ADOPTS LP2985-3.3, the voltage reaches 16V,increase the reliability, reduce the voltage problem probability of Bad Gyro health
uses jumper cap to choose, find the MAG pins on board, plugging in jumper cap is built in compass, taking off jumper cap is external compass
Added a 47 uf tantalum capacitor, improve APM on-board chip, the stability of the power supply.
