Descritption

Your power supply problems have just been solved! This small printed circuit board may sound tiny, but inside there is a high-performance DC/DC converter that can produce up to 3 amperes at 5V without the need for a heat sink or cooling system. (UBEC stands for Universal Battery Eliminator Circuit and this UBEC is designed to replace a 5V power supply in RC aircraft and helicopters, but it is also ideal for any type of microcontroller or electronic project that runs from 5V. We tried half a dozen different CLBs and found it to be the best in terms of reach and stability. You can see the technical tab for the analysis of the input/output range and current draw.

To use it, connect a 6V to 16V (recommended) power source to the IN wires and the 5V will be generated on the OUT wires. A regulated output of 5V (+-5%) from a higher voltage input will be obtained. Output current 3A, see 5A peak - if you try to pull 3A, you will have to give it a little more than 6V, at 7V it works fine. The UBEC has integrated filter capacitors on the input and output, but it is a switched-mode power supply and therefore slightly noisy compared to a linear controller.

We have removed the heat shrinkable from one and found that it contains an MP2307 that you can check the datasheet for conversion efficiency and other specifications.
