Based on NXP LPC4078+JN5168 multi-axis smart aircraft solution

With the development of science and technology, more and more attention has been paid to UAV technology. Compared with fixed-wing UAVs, multi-axis aircraft has many advantages: such as power distribution, symmetrical body mass distribution, large horizontal area, and no difference when adjusting inclination. Will produce translation.

The four-axis structure determines that it can rotate on any axis with its own center of mass as its origin, and can achieve difficult movements such as ascending, descending, left-handed, right-handed, forward, backward, left, right, and suspended. Due to the large horizontal structure area, it is suitable for the installation of aerial photography equipment. It is widely used in aerial photography, film, agriculture, real estate, news, fire protection, rescue, energy, remote sensing surveying and mapping, wildlife protection and other fields, and it is continuously integrated into new industries. application.

This multi-axis smart aircraft hardware and software solution includes the following parts: flight control board, remote control board, electronic control board (ESC), sensor board, flight control board we use NXP LPC4078 which is based on ARM Cortex-M4 core , Main frequency 120MHz, 512K Flash as the main controller, the remote control board uses NXP LPC1114 which is based on ARM Cortex-M0 core, main frequency 50Mhz, 32K Flash as the main controller, wireless control uses NXP JN5168 with power amplifier, the distance reaches 6 kilometers The electronic control (ESC) uses three solutions: Microchip PIC16F1938, Nuvoton Mini54, NXP LPC1517, the Sensor board uses BOSH BMI055 6-axis gyroscope, BMM150 geomagnetic sensor, and BMP280 air pressure sensor. In terms of software, we provide open source KK or German MK flight controllers for reference.
