This kit contains a slide toggle switch to turn the battery power on or off, and a reset switch to reset the microcontroller.
The slide toggle switch is a must if you are planning on using the Reviung41-LP with a Nice!Nano controller and battery. If you're using the Reviung41-LP wired, then you'll most certainly appreciate the reset button as well.
Note: this kit is included by default by the
Reviung41-LP Base kit.
