Tutorial: How to Use Raspberry Pi 4 X735 V2.5 Power Management & PWM Cooling Fan
The Raspberry Pi 4 X735 V2.5 Power Management & PWM Cooling Fan is an ideal module for anyone using a Raspberry Pi 4B, 3B+, or 3B. This module helps you keep your Raspberry Pi temperature under control and optimize power usage.

What do I need?
– Raspberry Pi 4B/3B+/3B
– USB connection
– Power supply

Steps:
1. Connect the module to your Raspberry Pi using the USB connectors.
2. Verify that the module is recognized by the Raspberry Pi operating system.
3. Configure the module through commands specified in the documentation.
4. Adjust the PWM fan for optimal cooling.
5. Check the temperature of your Raspberry Pi with system commands.
6. Enable the safe shutdown function in the operating system.
7. Monitor module activity and adjust any additional parameters.
8. Test the module’s functionality with various workloads to optimize cooling and power management.

Example code:
sudo apt-get update
sudo apt-get install lm-sensors
sudo sensors-detect
sudo modprobe w1-gpio
sudo modprobe w1-therm

Mini-project: Create a real-time temperature monitoring system for your Raspberry Pi using the X735 V2.5 module. Display the temperature on the Raspberry Pi screen and adjust the PWM fan to maintain constant temperature.

Common errors:
