Heating Pad - 5x10cm

The Sparkfun Heating Pad, sized at 5x10cm, is a DC powered pad designed for close-to-body heating applications. With a simple application of 5VDC to the wire leads, the pad starts warming up within minutes, reaching a comfortable temperature that's warm to the touch but not excessively hot. However, it's important to note that appropriate voltage should be maintained to avoid burns to bare skin, making this product unsuitable for beginners.

The design of these heating pads is unique and practical. They are made with a mesh of Polyester filament and Micro Metal Conductive Fiber, folded into a protective Polyimide Film. This results in a low-power, flexible pad that draws minimal power, making it an excellent choice for heated garments such as hand-warmers. With the addition of a microcontroller and some sensors, it's even possible to create a climate-controlled hoodie.

Key features of the Sparkfun Heating Pad include an operating voltage of 5V DC, an operating current of approximately 750mA (~6.5Ω), and dimensions of 5 x 10 cm.
