APM 2.8 Flight Controller
Are you want to be an Electronic Geek in the future and want to build your own drone then this Flight controller is best for you. The flight controller uses the data gathered by the sensors to calculate the desired speed for each of the four motors. The flight controller sends this desired speed to the Electronic Speed Controllers (ESC’s), which translates this desired speed into a signal that the motors can understand. This flight controller.

APM 2.8 Multicopter Flight Controller is an upgraded version of 2.5 and 2.6 with a Built-in Compass for FPV RC Drone. The sensors are exactly the same as the APM 2.6 flight controller. However, the module has the option to use the built-in compass an external compass via a jumper. This makes the APM 2.8 ideal for use with multi-copters and rovers.
The APM 2.8 Multicopter Flight Controller is a complete open source autopilot system. This is the best-selling technology that won the prestigious Outback Challenge UAV competition. It allows the user to turn any fixed, rotary-wing. In addition, it turns multirotor vehicles (even cars and boats) into a fully autonomous vehicle. meanwhile, it is capable of performing programmed GPS missions with waypoints. Featured By RoboticsBD.

APM Flight controller Using the built-in compass:
To use the built-in compass simply connect the jumper as shown below. The APM board will use the external compass, during the compass jumper is removed.
Features :
- Straight Needle
- Arduino Compatible
- Onboard 4 MegaByte Dataflash chip for automatic data logging.
- Optional off-board GPS, a 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.

NEO GPS M8N:
If you are wandering to navigate the distance with a drone then this GPS Module is needed for you. GPS drones are equipped with a GPS module that allows them to know their location relative to a network of orbiting satellites. Connecting to signals from these satellites allows the drone to perform functions such as position hold, autonomous flight, return to home, and waypoint navigation.
NEO-M8N High Precision GPS Module with Built-in Compass for APM and PIXHAWK FC is the new Neo-M8N GPS module that includes an HMC5883L digital compass. This module has a high level of sensitivity and features active circuitry for the ceramic patch antenna. It also comes enclosed in a plastic case to protect the module from the elements. This module outputs precise position updates at 10Hz and also has a rechargeable backup battery for warm starts. The NEO-M8N is configured to run at a baud rate of 38400 and can be used with Pixhawk and APM (you might need to modify the cable to fit your autopilot board).
NEO-M8N GPS Module for APM2.52 Flight Controller with Case and GPS Antenna Mount to protect the GPS preventing electromagnetic interference. A new generation NEO-M8N GPS Module, with low power consumption and high precision, the ultimate accuracy is 0.6 meters, actually almost 0.9 meters, greater than the previous generation NEO-7N 1.4-1.6 meters accuracy. Support GPS/QZSS L1 C/A, GLONASS L10F mode or more. The NEO-M8N and ceramic antenna make this a very accurate receiver, fast locks & lots of satellites, and the stand is very sturdy to protect the GPS preventing electromagnetic interference.
The most important improvement with this module is the vast sensitivity it offers. This module receives concurrent reception from GPS/QZSS, GLONASS, meaning that you should get an excellent signal no matter where you are in the world. Not only does it have these excellent reception capabilities, but it also maintains its low power consumption. This module is also backward compatible with the NEO-7, NEO-6, and NEO-5 families.
This module also comes with a circular mounting pad.
Note:
- When the GPS modules have power, the blue LED will flash for a second (probably less than a full second). It will then flash constantly once it has a position lock.
- This module comes with a genuine chip that enables you to update the firmware* and change the configuration via U-Center. However, if you do not need this functionality.
- Due to the flash memory of this specific module, you cannot update the V3.01 firmware as the firmware file is too big.
- This is a product of ReadyToSky brand powered by chip inside
- This module comes with 5 pin connectors connected by default (i.e.Ready to connect to APM FC) and an extra 6 pin connector for PIXHAWK FC for Swapping.
