These buck regulator boards feature the AP3429A from Diodes Inc., a 2A DC-DC buck converter with a wide input voltage range of 2.7V to 5.5V. The boards are configured to provide a regulated 3.3V or 1.8V output, which is controlled by an EN (enable) pin and indicated by a red power LED. A pre-assembled screw terminal and 0.1" spaced PTH pins are available to connect the input and output power of the boards. Additionally, there is the option to solder on a barrel jack for an external power supply. To dissipate excess heat, a copper pad is provided to attach a heat sink to the bottom of the board.
The primary differences between these boards are their regulated output voltage (1.8V and 3.3V) and the configured UVLO (2.7V and 3.9V, respectively).
