Arduino / Accessories / Power Supplies

This is a really nice power supply. It's a switching DC supply so it's small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 9V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel jack, positive tip. This supply is designed to work anywhere in the world, 100V-240V AC...

I found these high-quality battery clips. They're molded plastic so they won't tear like cheap clips, and they cover the battery terminals to prevent shorts. Comes with a 5.5mm/2.1mm center-positive barrel connector, assembled! Battery not included.

This is a 9V battery pack with on/off switch and a pre-attached 5.5mm/2.1mm center-positive barrel plug. Use this to battery-power your Arduino (or other electronic projects) - it's ready to go out of the box! Battery & screw not included.

This is a really nice power supply. It's a switching DC supply so it's small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 12V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel jack, positive tip. This supply is designed to work anywhere in the world, 100V-240V AC...

A smaller-sized rechargeable battery pack for your Raspberry Pi or Raspberry Pi B+ (or Arduino, or Propeller, or anything else that works with 5V!). This pack is intended for providing power to an iPhone, cell phone, tablet, etc but we found it does a really good job of powering other miniature computers and micro-controllers. If you want more power we have a 4400mAh...

What's a project if it's trapped on your desk? Now you can take your Arduino anywhere you wish with the PowerBoost shield! This stackable shield goes onto your Arduino and provides a slim rechargeable power pack, with a built in battery charger as well as DC/DC booster. Compatible with Arduino Uno, Duemilanove, Mega, Leonardo and Due - basically any...
