If you need further help optimizing this module for your project, let me know: Powering Arduino systems or ESP8266/ESP32 modules from dirty

Regulated, step-down DC output voltage (0.8V to 20V). The standard HW-133-V1

The standard HW-133-V1.0 on its input lines. Accidentally swapping the IN+ and IN- connections will instantly destroy the MP1584EN regulator IC. If your application runs a risk of battery reversal, place a low-forward-drop Schottky diode in series with the IN+ line. Tuning Setup Advice

Converting a 12V or 24V lead-acid battery for USB charging (5V).

The HW-133-V1.0 board typically features four clearly marked pads for soldering, ensuring straightforward integration into projects. Positive input voltage (4.5V - 28V) IN-: Input Ground (GND) OUT+: Positive Output Voltage (0.8V - 20V) OUT-: Output Ground (GND) Important Connection Notes:
