DC -> DC Voltage Step-Up module, 4-27V, *NEW* 5V USB-powered
This compact circuit board module can provide a user-adjustable 4-27V DC output on the Vout terminals, which is adjusted by trimming the on-board potentiometer. This module can be used to provide DC->DC Voltage Step Up Boost, giving for example 6V / 12V / 24V output as desired (continuously variable) from either a 3.7V Lithium battery or the 4-8V / 5V USB input. The following U-Tube video shows some of these uses: https://www.youtube.com/watch?v=rVLlKuDx0tM It can be used (for examp
