  • 18650 3.7V Lithium Battery...


    A single cell 18650 lithium battery holder with +Ve (red) and -Ve (black) solderable fly leads to allow easy connection screw terminals or soldering to a PCB. Once inserted the battery is held very firmly but can also be removed for recharging or replacement without requiring tools. There is a single screw hole at the base of the holder for permanently mounting using an M3 countersunk screw.

    For Battery type: 18650 3.7V Lithium battery
    Dimension (LxWxH): 76mm x 21mm x 18.5mm
    Wire length: 140mm (approx)

  • Hobby Components Lithium...


    The Hobby Components micro charger is a tiny single cell (3.7V) lithium battery charger module which not only incorporates both battery charging protection and control, but also includes battery voltage & current over discharge protection and battery overload protection. Measuring only 27 x 14mm this tiny module can easily be incorporated into low power lithium battery applications.

    The charger will accept power from either a 5V microUSB adapter or via a 4.5 to 6V power supply and will charge a connected single cell lithium battery at a rate of ~0.5A.

    The battery can be connected via a JST XH-2.54 connector or by 2 large solder pads (BIN + & BIN -).

    The module's output supplies the batteries nominal output of 3.7V (4.2V whilst charging) at a constant current of up to 2A (depending on battery and charger specification). An external device can be connected to this output via a 0.1” pitch pin header or via 2 large solder terminals (BOUT + & GND).

  • Hobby Components ESP-ARGB...


    The ESP-ARGB is a general purpose RGB+W LED light controller based on the popular Expressive ESP8266 wireless microcontroller. It combines an ESP8266 ESP-07 wireless module with four MOSFET transistors. These transistors are connected to the ESPs PWM output pins making it easy to perform independent power control of up to 4 connected devices. Each transistor can switch up to a maximum current of 2A and a maximum voltage of 12V DC.
