    Simple Delay Timer Circuit

    This is a very simple timer circuit. When you push down to turn on the S1, this will turn on the LED and it also will charge the C1 Capacitor. Then upon releasing the push button switch, the LED will stay lit for couple of seconds until C1 is completely discharged.

    Flora Mainboard

    FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is designed to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size. The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric.
