This tiny coin cell battery holder is ideal for small portable or wearable projects. It holds one 20mm coin cell (also known as CR2032) in series to generate 3V nominal. 20mm coin cells are popular as they are used in keychain lights and remotes, so they are easy to get and fairly low cost. They tend to have about 220mAh capacity.

This tiny coin cell battery holder is ideal for small portable or wearable projects. It holds one 20mm coin cell (CR2032 is the most popular size) to generate 3V nominal. 20mm coin cells are popular as they are used in keychain lights and remotes and other small topys, so they are easy to get and fairly low cost. And speaking of lights, these battery holder includes three "LED" modes: quick flashing, slower flickering, and static on. Press the button to cycle through the modes. Although designed for LED jewelry, it could be used for other projects that need simple cycling.

This is a generic rechargeable AAA NiMH battery with a capacity of 900 mAh. These batteries are well-suited for powering small- to medium-sized robots and can be used with Pololu's AAA battery holders. You will need to charge these batteries before you first use them.

The S7V8A switching step-up/step-down regulator efficiently produces an adjustable output between 2.5 V to 8 V from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most combinations of input and output voltages.

The Pololu Pushbutton Power Switches are sophisticated power control alternatives to bulky mechanical switches. The main function is pushbutton-based latching power control, where one push turns on power and another push turns it off. Additional control inputs allow advanced applications such as automatic shutdown by the device being powered. This low-voltage (LV) version operates from 2.2 V to 20 V and can deliver continuous currents up to around 6 A.
