This design allows user to select positive or negative logic remote control. This demo board only

implements the negative logic remote control circuit. To change to positive logic, remove Q5, R7, R8,

and R12.and add D2 andD3.

Over temperature protection:

The over temperature protection will shut down the module when abnormal high temperature is detected

by the circuit.. The module will attempt to restart once the temperature cools down. The temperature set

point can be adjusted by resistor R11.
