DC/DC STEP-UP converter MT3608 5-28V 2A, microUSB connector

This is almost the same module like MOD-1134, uses MT3608 to convert voltage. Difference is in connector. This module has microUSB connector soldered in, so You can easily connect any USB charger and get higher voltage on output. There are still pads for soldering wires with input voltage, so You can still use this module with input voltages different than 5V.
