schematic:\
Tiny module is a PWM Solenoids and Valves driver using Texas instrument’s DRV103 low-side DMOS power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, motors and positioners. This board is also ideal for driving thermal devices such as heaters, coolers, lamps, PWM operation conserves power and reduces heat rise, resulting in higher reliability. In addition, adjustable PWM allows fine control of power delivered to the load. Output delay time and oscillator frequency are also externally adjustable.
