Knife Switches come with plastic base and brass fittings.
This board operates at 3.3V and features a JST socket so you can directly connect a Li-Po battery for power and an on-board power switch so you can turn it off when you’re not feeling particularly blinky. These boards were designed to streamline your next project by keeping things simple and giving you more room to work while eliminating the need to add a power supply. The LiPo battery is even rechargeable through the board, no more special external LiPo chargers required! The only extra piece of hardware you need to program the LilyPad USB is a micro-USB cable, since the new IC has built-in USB support. The LilyPad USB is also officially supported in the Arduino IDE as of version 1.0.2! Measures 50mm outer diameter and 0.8mm thin.
