QX5252 Solar LED drive board
Solar LED drive board
It is used with solar power elements together with Ni-Cd batteries.
- Operating voltage range: 0.9 ~ 1.5.
- Size: 22 mm x 12mm x 5 mm
In the presence of light-charges the battery from the solar cell, in the absence of light-includes generation and feeds the LEDs current, depending on the value of inductance (~ 150uh = 25mA). When the voltage falls on the battery below 0.9 v-disables generation and waits for light.
