The MT8870 DTMF Audio/Speech Decoding Telephone Module is commonly used to control robots with a mobile phone, it is also used in different kinds of home automation projects where mobile dial pad input is required.
The TB6612FNG is a motor driver red color module, it can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes.
The MT3608 Step-up converter (Output voltage higher than input). Supply voltage 2-28V, output max. 28V at max 2A. Avoid the state when the input terminals have higher voltages than those set on the output terminals. The drive chip may be damaged.
The S8050 is a low voltage high current small signal NPN transistor, designed for Class B push-pull audio amplifier and general purpose applications. S8050 0.5A/40V NPN Transistor TO-92.
The BUX98A is a multi-epitaxial mesa NPN transistor in TO-3 metal case, intended for industrial applications from single and three phase mains operation.
The PWM transfer voltage module LC-LM358-PWM2V converts the PWM digital signals into 0 to 10V analog signals. It can be used as signal interface switching for PLC or other industrial control boards.
The MJE13007 is designed for high−voltage, high−speed power switching inductive circuits where fall time is critical. It is particularly suited for 115 and 220 V switch−mode application.
