Description: 1. LM2596S and LM2577S are adjustable DC-DC buck and boost power supply modules based on the Linear Technology LM2596 and LM2577 chips, respectively. These modules offer step-up (boost) and step-down (buck) functions for voltage conversion in IoT projects. 2. Input Voltage: The modules accept a wide input voltage range of 8-35V DC for LM2596S and 10-36V DC for LM2577S, making them versatile for various power sources in IoT applications. 3. Output Voltage: The adjustable output voltage ranges from 1.5V to 24V for both modules through a single potentiometer on the PCB. This feature enables precise voltage regulation and caters to diverse power requirements. 4. Efficiency: With an efficiency rating of up to 80%, LM2596S and LM2577S minimize energy wastage, making them economical solutions for IoT projects where low power consumption is essential. 5. Protection Circuitry: Integrated over-voltage (OVP) and short-circuit protection safeguards the modules from potential damages during op
