 ===== Description =====
-The Quad Temperature Controller Board (ICE-QT1) provides 4 independent PID temperature servo loops capable of sub-mK stability(( Sub-mK stability requires a proper thermal design and proper tuning of the temperature controller to the thermal plant. If you did not purchase the Laser Controller with a Laser Diode, please read the section on tuning the temperature controller.)). Each channel can drive either a single TEC (bipolar current output) or resistive heater (unipolar current output) and read a single 10k thermistor.
