To operate LEDs, a voltage of about 2V is necessary, with white and blue LEDs even about 3V.
This module allows the operation of LEDs on only one or two rechargeable battery cells in a range of 0.9V to 2.6V.
Please note that the voltage input 1.2V unlike the 2.4V input is not reverse polarity protected. We recommend for trouble-free operation max. 4 LEDs at the output. More are possible depending on the circuit type and LED.
You have the option of operating on the converter output LEDs in series, parallel or in a mixed circuit, such as two red LEDs in series // to two white LEDs in series. In a series circuit, it is not recommended to mix LEDs of different colors.
Technical specifications Prefab module with connection cable Output current: approx. 12mA IC Type: PR4401 Prema LED driver Board dimensions (L x W x H): 10 x 7.5 x 3.5mm Length of connection cable: 100mm Voltage input RED: from 0.9V to 1.9V Voltage input LILA: from 1.6V to 2.6V
