Coin Cell Battery Holder

Lithium coin cell batteries are thinner than button batteries and have a higher voltage. They are used to power devices like scales, key fobs and flameless candles.

Proto-Pic have tiny coin cell battery holder which 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. The holder is made of plastic and snaps open and closed with two tiny screws. There is a 13cm-long plain wire on the end, for easy attachment or soldering to whatever circuitry you wish to power.

BabyBuck Regulator Breakout

Proto-Pic also have BabyBuck Regulator Breakout 3.3V, AP63203 which is long lasting and heavy duty. Featuring the AP63203 from Diodes Inc, this breakout board takes advantage of a 2A synchronous buck converter that has a wide input voltage range of 3.8V to 32V and fully integrated 125mΩ high-side power MOSFET/68mΩ lowside power MOSFET to provide high-efficiency step-down DC/DC conversion.
