SparkFun Power Supply Sample Kit

The SparkFun Power Supply Sample Kit is a comprehensive collection of power supplies designed to meet the needs of various development boards. This kit includes four high-quality wall adapter power supplies with different voltage outputs - two at 5V, one at 9V, and one at 12V. The first item in the kit is a USB Wall Charger that outputs 5V at 2A. This switching 'wall wart' power supply is perfect for powering your USB devices when a computer is not readily available. The output is regulated to 5V, ensuring a steady and reliable power source.Next, there is a Wall Adapter Power Supply that also provides 5VDC at 2A, but with a barrel jack connector. Like the USB charger, this 'wall wart' is a switching power supply, meaning it regulates its output to a stable 5V. It can provide a much higher output current, up to 2000mA, making it an excellent choice for power-hungry devices.The third item in the kit is a Wall Adapter Power Supply that delivers 9VDC at 650mA through a barrel jack connector. This high-quality 'wall wart' power supply is also a switching power supply, regulating its output to 9V. It can deliver a higher output current, up to 650mA, making it suitable for devices requiring a 9V power source.Finally, the kit includes a Wall Adapter Power Supply that produces 12VDC at 600mA, also with a barrel jack connector. This AC to DC 'wall wart' is a switching power supply, regulating its output to 12V and providing a higher output current, up to 600mA.With the SparkFun Power Supply Sample Kit, power supply concerns for your next project will be a thing of the past. However, remember to include a USB Cable for your project if you plan on using the USB Wall Charger and don't have one already.The SparkFun Power Supply Sample Kit includes:

* 1x USB Wall Charger - 5V, 2A * 1x Wall Adapter Power Supply - 5VDC, 2A (Barrel Jack) * 1x Wall Adapter Power Supply - 9VDC, 650mA (Barrel Jack) * 1x Wall Adapter Power Supply - 12VDC, 600mA (Barrel Jack) For more information about each product, please refer to the individual datasheets and the Unregulated Power Supply Tutorial provided by SparkFun.
