snapVCC is a highly portable and convenient power supply for your electronics projects. It’s designed to fit right on a 9V battery.

What can you do with snapVCC?

Many circuits require a regulated 3.3 or 5 volt power supply. The 9V battery is an easily available power supply option. A common way to power circuits using a 9V battery is to use a Linear regulator IC circuit to drop the voltage down. snapVCC eliminates this additional circuit by putting the regulator right on top of the 9V battery. Also, since snapVCC uses a buck converter, it’s more efficient than using a linear regulator.


  • Texas Instruments TPS560200 buck converter with 500 mA output current
  • 3.3 V / 5 V output, switchable via jumper
  • P-MOSFET for reverse polarity protection
  • Power indicator low power LED
  • Tiny form factor, sits on top of a 9V battery
  • Power headers are standard .1” pitch
  • Comes with a jumper cable for plugging into a breadboard


snapVCC uses a buck converter for efficient regulation of battery voltage. snapVCC has an LED power indicator, reverse polarity protection, and you can switch between 3.3V and 5V by just switching a jumper.
