1 2 3 4 Button Key Membrane Switch Matrix Keypad Matrix Control Panel Pad DIY Kit for Arduino in Pakistan

Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full); 2. Increased input reverse polarity protection diode; 3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).Particularly suitable for LED driver *High-power LED constant current drive *Lithium battery charger (including ferroelectric)

This module is based on a touch detection IC (TTP223B) of Capacitive type touch jog switch module . This module default output low, the low-power mode to mode; when a finger touching the corresponding position, the module will output high and returns low again touch. Mode is switched to fast mode; when for 12 seconds without touching
