Summary

This circuit is designed to control four brushless motors using corresponding electronic speed controllers (ESCs). It includes a power management module (Pm06 v2-14s) to distribute power from a Lipo battery to the ESCs and other components. The Arduino Mega 2560 serves as the main microcontroller, interfacing with an NRF24L01 wireless module for remote communication. A logic level converter is used to safely interface the 3.3V logic of the NRF24L01 with the 5V logic of the Arduino Mega. Additionally, a 6pin JST-GH Cable is used for voltage and current sensing from the power management module to the Arduino. The circuit is designed for applications such as drones or other remote-controlled vehicles where precise motor control is required.

Documented Code

Arduino Mega 2560 Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a template for the Arduino Mega 2560. The setup() function runs once when the microcontroller is powered on or reset. The loop() function runs continuously after setup() has completed. The user will need to add the specific code for initializing the ESCs, reading sensor data, and handling wireless communication with the NRF24L01 module.
