Product description: SparkFun Buck Regulator Breakout - step-down converter 1.8 V 2 A - AP3429A - SparkFun COM-21338
Step-down converter equipped with the AP3429A voltage regulator by Diodes Inc. The module lowers the input voltage, which is in the range from 2.7 V to 5.5 V, giving the output voltage 1.8 V (current efficiency is 2 A ). On the back of the board there is a copper washer to which a heatsink can be attached to dissipate excess heat generated by the system during operation.

Description of the module pins
The board has outputs in the form of solder pads, to which wires should be soldered and connected according to the following dependencies:
- VIN - input voltage from 2.7 V to 5.5 V
- GND - system ground
- VOUT - output voltage (adjustable 1.8 V)
- EN - control pin
In addition, the module also has a screw connection, which is an alternative connection.
