This is a DC-DC boost converter module with an XL6019 boost chip that supports 3V-35V input and 5V-45V adjustable voltage output with high current output up to 5A. The on-board potentiometer and 3-digit red LED for output voltage adjustment display the pushbutton-controlled input / output voltage for easy operation.

This is a high voltage step-up power supply module, which is commonly used in electronics experiments and demonstrations. The module can generate a voltage of up-to 1000KV from an input of 3.3-5V from a normal Li-ion battery. The high-voltage module uses the principle of the Tesla coil.
