This is the new APM 2.6 autopilot module. The sensors are exactly the same as with APM2.5+, however this version does not have an onboard compass, which makes this version ideal for use with multicopters and rovers.

The APM 2.6 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:
- Arduino Compatible!
- Can be ordered with top entry pins for attaching connectors vertically, or as side entry pins to slide your connectors in to either end horizontally
- Includes 3-axis gyro, accelerometer and magnetometer, along with a high-performance barometer
- Onboard 4 MegaByte Dataflash chip for automatic datalogging
- Optional off-board GPS, uBlox LEA-6H module with Compass.
- One of the first open source autopilot systems to use Invensense's 6 DoF Accelerometer/Gyro MPU-6000.
- Barometric pressure sensor upgraded to MS5611-01BA03, from Measurement Specialties.
- Atmel's ATMEGA2560 and ATMEGA32U-2 chips for processing and usb functions respectively.

GPS Features:
- Built-in compass GPS module
- Main chip: Ublox-6H
- With fast satellite searching speed and high precision
- Compatible with APM serial port and I2C port
- Includes round plastic shell and GPS support

 3DR Radio Telemetry Kit 433Mhz OR 915MHZ

-The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee radios. It’s availabl in 433Mhz; and in the following configurations:  serial board (for the air) and USB (for the ground). 
- The radio is a 2-way half-duplex wireless communication system with a standard TTL UART interface, based on HopeRF's HM-TRP data link modules, and custom firmware that improves upon the modules' original features and performance. 
- The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and radio firmware with configurable parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through AT commands.

 MAVLink-OSD V2.0

Introduction

- MAVLink-OSD is an Arduino based project and it is fully compatible with original MinimOSD.
- This board can be used for CRIUS AIOP and Arduflyer / ArduPilot-Mega.
- MAVLink-OSD with switching DC/DC stepdown powersupply to maximize efficiency on power system. No more heating problems when using this OSD board.
- Default OSD Firmware is MinimOSD-Extra, written by Gábor Zoltán.
- About how to use the configurator tool to setup OSD function: Click here
- How to setup hardware (original MinimOSD Wiki): click here

Power Module is a simple way of providing your APM/Arduflyer with clean power from a LiPo battery as well as current consumption and battery voltage measurements, all through a 6P cable. The on-board switching regulator outputs 5.3V and a maximum of 3A from up to a 7S LiPo battery.
Note: The Power Module is only designed to power APM/Arduflyer, a RC receiver and accessories (GPS, Radio telemetry). It is not designed to power servos. Use your aircraft's own ESC/BEC for that.
