From the back, there are two PCB boards that make up the Kingwin Thermal Center. One PCB is for the controller chip, and the other for attaching connectors. Both the PCB's are separated by four motherboard brass stand-offs. The unit uses the Holtek 8 bit HT49R50A-1 controller, which features an 8 bit high performance RISC micro controller that can handle up to 63 instructions. The controller has been designed for a wide range of LCD applications.
