Circuit Documentation
Summary
This circuit appears to be designed for a multi-motor control application, possibly for a drone or a similar vehicle that requires independent motor control. It includes an Arduino Pro Mini as the central microcontroller, interfaced with a GPS module (GPS NEO 6M), a wireless communication module (NRF24L01), and a motion tracking sensor (MPU-6050). The circuit is powered by a Lipo Battery and uses four Electronic Speed Controllers (ESCs) to manage the power and control signals to four Brushless Motors. The ESCs also provide a 5V output that powers the Arduino and the sensors.

Documented Code
Arduino Pro Mini Code (sketch.ino)
void setup() {
}
void loop() {
}
The provided code is a template with empty setup()
and loop()
functions. The setup()
function is intended for initialization code that runs once at startup, and the loop()
function contains the main logic that runs repeatedly. Actual implementation details need to be added based on the specific requirements of the application.
Additional Notes
- The code for the Arduino Pro Mini is minimal and does not include any functionality. It needs to be populated with the logic for reading sensors, controlling the ESCs, and handling wireless communication.
- The NRF24L01 module requires a 3.3V power supply, but it is listed as connected to a 5V output. This needs to be corrected to prevent damage to the module.
- The documentation file for the code is empty and should be updated with relevant information as the code is developed.
