This open board temperature controller is specifically  
designed with a proportional integral control algorithm to
provide the most precise control to thermoelectric (Peltier
effect) modules at the most economical price.
The H bridge control provides a seamless transition    
between heating and cooling, eliminating dead spots. A
red LED for heat and green LED for cooling indicate
mode. Pulse Width Modulation controls the power level in
the thermoelectric module at a base frequency of 900Hz.
Power resolution is one of ±255 steps in the load circuit
