This epoxy-encapsulated monocrystalline solar cell offers 6.7V and 20mA in a 37x33mm package. Now updated with the Miller Engine circuit!
2A Booster DC-DC Step-Up module Micro USB Input 2V-24V to 5/9/12/28V
This adjustable buck converter takes a higher voltage and efficiently cuts it down between 1.23~30VDC, without wasting the power a linear regulator or resistor will.
This is a coin cell holder for the common CR2032 type battery. The holder has a neat pop-in, pop-out feature that makes changing the battery easy.
These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry.
Simple LiPo single-cell charger from Sparkfun, with a Micro-USB cable connector.
Switching Power Supply - Perfect for Arduino Uno projects!
When mini buck converters just won't do, 200W should manage it nicely.
Add a High Capacity Rechargeable power supply to your project easily!
DC-DC Converter Step Down Power Module LED Display Output 1.25V-37V
This high discharge 2-cell LiPo is a great way to power any R/C, robotic, or portable project. This is an excellent choice for anything that requires a small battery with a lot of punch.
Simple, no-brainer method to charge up a single cell Li-Ion / LiPo battery.
PowerBoost 1000 Charger - Rechargeable 5V Lipo USB Boost @ 1A - 1000C
3.7V 400mAh LiPoly battery with an excellent 2C discharge rate for small projects.
Need more power at 5V? These guys can lift 20 times their body weight!
Need more 7V5 power? These guys can lift 20 times their body weight!
Got a stepper driver running a bit too hot? Vreg going into thermal shutdown? Here's a heatsink, for small applications.
1.25 ~ 35V Buck/Boost Regulator with 3A current capability
These are small 1/8" square clear-epoxy encapsulated solar cells generating about 1/2 volt @ 1.9mA in sunlight.
This epoxy-encapsulated monocrystalline solar cell generates a nominal 4.5V / 18mA (sunlight) from a 24x33mm package. And has an integrated solarengine circuit board!
This big brother of the SCC3733 is also an epoxy-encapsulated monocrystalline solar cell, but this one offers 8 volts and 44mA in a 37 x 66mm package!
Standard 9V battery connector.
For builders of smaller robots, here's a holder for a pair of AAA batteries.
Need to hold a pair of AA batteries?
It's a nice quad-AA battery holder, with 6" leads.
