The BPW34 is a tiny, general purpose PiN photodiode. This photodiode has a ton of uses, one of which is to use it is a mini solar cell to power your project. The cell is sensitive to a wide range of light wavelengths (430-1100nm), so it should produce power in a number of diff...

DF-DFR0579

Solar Power Manager Micro is a micro power, high-efficiency solar power management module, designed for powering IoT based low-power wireless sensors or controllers with 1V~3V small size solar panels. Benefited from its extremely low power dissipation and MPPT (maximum power p...

Simple but effective - this breakout board has a CR1220 coin cell battery holder soldered on, an on/off switch and 0.1" pitch breakout pins for easy connecting. Great for powering very low-current projects, or adding a battery backup circuit to a real-time-clock or similar. Th...

AF-653

This battery holder is by far the easiest way to add a battery to a small wearable project. By coincidence, there are two small 1mm diameter holes in the metal connection tabs, just large enough for a #5 or smaller needle to pass through. One tab connects to common ground (neg...

Now for all of your coin cell battery surface mount needs, the 20mm SMD Coin Cell Holder. This holder fits our 20mm Lithium Ion coin cell battery and holds the battery in place with friction. The metal housing connects to the positive (+) side of the battery and the PCB pad un...

SF-PRT-00338

CR2032 Lithium metal 3V 250mAh button cell battery. Great for powering low power processors or blink an LED for weeks at a time.

SF-PRT-00337

CR1225 lithium metal 3V 12mm 47mAh coin cell batteries. Perfect small battery for miniature sensor node applications.

SF-PRT-11305

These LR44 button cell batteries are fairly common but it can be hard to keep them around. They fit our digital calipers, so if you use yours as much as we use ours, you may want to go ahead and pick up a spare.

Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use.

AF-80

I found these high-quality battery clips. They're molded plastic so they wont tear like cheap clips, and they cover the battery terminals to prevent shorts.

AF-368

If you need to connect a DC power wall wart to a board that doesn't have a DC jack - this adapter will come in very handy! There is a 2.1mm DC jack on one end, and a screw terminal block on the other. The terminals are labeled with positive/negative assuming a positive-tip con...

This battery holder features two 6", 24-gauge leads that have 5 mm of insulation stripped off of the ends.

AF-4030

This cable will let you turn a JST PH 3-pin cable port into 3 individual wires with grippy mini alligator clips. We're carrying these to match up with any of our boards or breakouts with 3-pin 'STEMMA' connectors on them such as the HalloWing or NeoTrellis M4.

LB-LS0040

Power your next project using the Australian Sun with this solar panel. The panel is capable of 3.5 watts in the open sun with a peak power output around 6V at 580-600mA.

Overview

SF-PRT-10218

These are your standard 9 Volt alkaline batteries from Rayovac. Don’t even think about trying to recharge these. Use them with Arduinos or with a voltage regulator to get a solid 5V for your project.

PL-1155

This battery holder features two 6", 24-gauge leads that have 5 mm of insulation stripped off of the ends.

SF-PRT-10288

This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard, this might be the simpl...

PL-2831

The D24V10Fx family of step-down voltage regulators features the Intersil ISL85410 1A synchronous buck regulator and generates lower output voltages from input voltages as high as 36 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC ...

NOTE: This product is only designed for use with solar panels sold at the Adafruit store.

FT-RELAY8

Drive up to 8 relays from your Arduino using just 2 I/O pins with this shield. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Includes back-EMF protection and works with a wide range of relays. Perfec...
