Power Adapter Module for DIY projects, 5V DC-DC converter

Perfect 5V power adapter module for use with breadboards. DC-DC converter that reduces the voltage from up to 18V to 5V. This is a switching step-down converter. In comparison with dropout converters: Energy-efficient Compact Reliable. Have additional security features Incredible size - 0.5"x0.3" (13x8mm) allows you to place it in any project. If you need to get a full power up to 1A, you may need to attach a heatsink. In my tests, I used a 15x20x9mm aluminum MOSFET heatsink. Features:  5V power output 4.8-18V power input 1A max load (When the heatsink using) 700mA nominal load (12V input) Power-good indication LED Input power indication LED Shor-circuit protection Overheat protection Reverse polarity protection  Refer to manual and detailed specification on the product page here   Important Safety Note:  Handle carefully! Hot surfaces!When the output current exceeds 700mA, the temperature of some PCB components may reach 230°F (110°C). When the output current is 500mA, the temperature may reach 170°F (75°C)
