PC or Smartphone) where the telemetry RX module is plugged in telemetry works at a frequency of 433 MHz. The GPS and telemetry TX module are used to transmit respectively aircraft position and general flight data like attitude or battery consumption to the ground station (e.g. The power module converts battery voltage (LiPo 3S or 4S) to the proper stable voltage of 5.3V (with a maximum current of 2.25A) needed from the controller and delivers it also to the ESCs it also measures battery voltage and current consumption, and sends these data to the APM. This kit, other than the APM controller, includes the following components: CRIUS power module, GPS, telemetry modules (TX and RX), shock absorber and connection cables. Moreover, since the ESCs have a BEC (Battery Eliminator Circuit) we need to connect only the signal wire and leave the positive and black wires disconnected. In this case, since we are going to use a power module that distributes the power along the board, we have to remove JP1. There is also a port for connecting the board to a PC through USB in order to install/update the firmware or programming the APM.Ī particularly important element on the circuit is the jumper JP1: depending on the chosen power configuration (using power module or taking power from ESCs) you have to remove it or leave it in place:

It features also a series of inputs and outputs pins respectively for receiver channels and ESCs (Electronic Speed Controllers) command signals. It has ports to connect GPS, telemetry and power module. It features an Atmel ATmega 2560 microcontroller and a series of sensors like gyroscope, magnetometer and barometer (the last one is covered by foam to reduce disturbances). The arrow with the “Front” tag indicates the direction that the controller interprets as forward.

The main component of this kit is the controller, the APM: I chose to have the red arms as the front of the quadcopter, while the white ones represent the rear (this is a completely arbitrary choice and depends on how the controller is oriented). 450 mm (considering the distance from propeller center of rotation to the opposite one).Īs the previous image shows, this frame has an integrated power distribution board (PDB) which simplifies the connections reducing the number of wires floating around the aircraft. This frame is a nylon and fiber glass structure: the number stands for the length of each line of the cross frame, i.e. In the case I cannot find the same component I used, I have put a link where you can buy a similar one.

In this section it is reported a list of the components used for this project with a short description of their most important features and a link to it. In this article I will show the build of a quadcopter made with a 450 frame kit using APM 2.6 with ArduCopter firmware version 3.2.1 as controller: this system performs attitude control and can be programmed for the execution of autonomous missions using PC (via Mission Planner software) or Smartphone (via DroidPlanner app).
