300W 20A Step Down DC-DC Buck Converter with Constant Voltage and Current Control [C] Pressure Sensor 1× MC14071 - Quad 2-Input

1× MC14071 - Quad 2-Input OR Gate IC - DIP-14 Package

Configurable IIC Address

This is a DIY version Spot Welding Machine that can be used for welding 18650/26650/32650 and other lithium batteries

To use this module take care that it must be used in a dark closed room as it is a non modulator Receiver so sunlight and others might affect it

This low-cost Laser Diode or Laser Light is commonly used in security devices and pointers

300W 20A Step Down DC-DC Buck Converter with Constant Voltage and Current Control [C] Pressure Sensor 1× MC14071 - Quad 2-InputBuck converter is used when you require to step down the DC voltage from a specified value to a lower value in DC voltage. Unlike AC voltage which you can control easily with a transformer, DC voltages are harder to control because you cant use a transformer to control it and it requires switching regulators to do so. This 300W 20A DC DC Step down Adjustable Constant Current Module can be used to get adjustable output voltage ranges from 1. 2V to 36V.
