The Loomia 5V - 7.2V Heater is made to work with an off the shelf, 5V battery pack or two lipo batteries in series (just make sure both can output 2A safely) and will get hotter depending on the voltage you use. The heater warms up quickly with tangible heat within 60 seconds and a top heat after 2 min. Use this component for heating wearables, or for thermochromic effects.
Loomia parts are designed to be easily soldered together, and work well with popular micro controllers like Arduino Nano and Teensy. The system revolves around Loomia's custom interconnect, which allows for a simple connection between buses. The interconnect can be soldered to headers for easy breadboarding. From fabric to wood, Loomia components can stick onto a range of materials, making your prototypes look clean and polished.
Note: There are a number of operating procedures to be aware of before using Loomia products. This includes directions to not wash or sew any of the parts. Make sure to check the Datasheet in the Documents tab for more information.
