APM Flight Controller Set APM 2.8 6M GPS & OSD w/ Radio Telemetry
433Mhz or 915Mhz

Brief Description:
Product Brand: APM
Product No. : APM 2.8
Product Name: APM Flight controller set

GPS:
6MGPS
Power supply cable: the default style of APM
Compass: 6M/6H
Terminal outgoing lines: compatible with APM serial port and I2C port

Telemetry:
The 3DRobotics 3DR Radio is the ideal way to setup a telemetry connection between your APM and a ground station. Small, inexpensive and with great range, the 3DR radio uses an open source firmware which allows us to do things that cannot be done with other radios.
- With protection case
- Very small size
- Light weight (under 4 grams without antenna)
- Available in 900MHz or 433MHz variants
- Receiver sensitivity to -121 dBm
- Transmit power up to 20dBm (100mW)
- Transparent serial link
- Air data rates up to 250kbps
- Range of approx 1 mile
- MAVLink protocol framing and status reporting
- Frequency hopping spread spectrum (FHSS)
- Adaptive time division multiplexing (TDM)
- Support for LBT and AFA
- Configurable duty cycle
- Built in error correcting code (can correct up to 25% data bit errors)
- Demonstrated range of several kilometers with a small omni antenna
- Can be used with a bi-directional amplifier for even more range
- Open source firmware
- AT commands for radio configuration

Power Module(with BEC):
Used to test battery voltage and current, flight control board, the two reception battery remaining power calculation, estimate the remaining time of flight.
Maximum input voltage 6S, measures the maximum current is 90A, realizes the control of slabs and the voltage of the battery capacity monitoring. Voltage current detection of Dr Official design parameters, design parameters and 3 ground station (mission planer) can directly refer to the official Wiki Settings

OSD:
APM has an companion OSD board called MinimOSD. It reads all the MAVLink data in the APM telemetry stream and overlays it on the video stream if you're using an on-board camera and wireless video transmitter. This is useful if you're flying in First Person View (FPV) mode or don't want to use a laptop at the field to see your telemetry data in the Mission Planner.
Note: This is an open source module

APM 2.8 Features:
- 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 multi-functional 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
- 2.8 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
- v2.5 just added gigahertz frequency component of the filter circuit which made of 0.1uF to filter the high frequency interference,the board does not have a large capacity of capacitor use to filter the low frequency component of the ripple,2.8 Added a 47 uf tantalum capacitor, improves APM on-board chip, the stability of the power supply.
