Transistor Curve Tracer On USB, for bipolar trannies and FETs

摘要

As can be seen from the schematic diagrams, the hardware is divided between two PCBs. The small microcontroller board (Figure 5) holds the R8C/13 and the PL2303, along with the associated components (Figure 2a). The main board (Figure 6) contains the rest of the hardware (Figure 2b), including the transformer.rnAll of the components on the microcontroller board are SMDs, so a reasonable amount of soldering experience is necessary for assembly. The main board is more roomy, and all of the components have leads or pins. The two 12-V voltage regulators, as well as power transistors T3 and T4, are fitted with heat sinks.
