This board does not includes any sort of voltage regulator. Make sure to supply correct Vcc (1.9 to 3.6 V) for this board. Connecting directly to 5V MCU (like Arduino without 3.3 V voltage regulators) will burn this sensor. This is a minimal circuit from "Typical Application Circuit" section from the datasheet.

License: CC BY-NC-SA 2.5 AUThe board is designed to measure the battery level (voltage) with an uC's ADC. The on-board voltage divider must be parameterized (R1 and R2) according to the uC's max ADC input as well as the battery's voltage level. The battery voltage may be higher then the ADC's Vcc.
The circuit includes two MOSFETs to cut-off the voltage divider in order to not drain the battery when not in use. The uC must pull up EN to activate the voltage divider. If EN is left floating (e.g., the uC is turned off or in deep-sleep), the on-board pulldown resistor cuts of the voltage divider.

If converting to LED you may want to use multiple bulbs in one socket to increase the load on the power supply in order to prevent flickering or to increase the light output. This adapter plugs into each halogen socket and provides two female sockets for two LED G4 bulbs. The pins and sockets are commonly available 2.54mm spacing female and male header. The male pins on the supply location would be best if they were longer such as 12-15mm.
