Maybe an optional daughter board that routes the main PIC pins and high voltage signals to the correct pins for the target using the main PCB socket or with a socket on the daughter board for other types of packages. Daughter cards could have stacking connectors to allow other cards to be connected at the same time. Dual channel 100 Mhz Digital Sampling Oscilloscope and 8 channel Logic Analyzer. Really clean user interface software. The entire design is open and available for download free of charge.
Optional extensions are without limit.
Most 50 ohm coaxial cable has a V factor of .66, and the pulse goes out and comes back, so figure .33C as a starting point. With this type transformer, there is almost zero leakage inductance, so almost no losses from snubbers, etc. in the primary. They have a limitation of fifteen volts, but yield an easy way to build a 300kHz to 1 MHz switcher. On the secondary, be sure to use Power Mosfets as synchronous rectifiers, so that ON resistance is perhaps .05 Ohms when they conduct and diode losses are virtually non-existent. In other words, you drive the Mosfets on only when the diode they replace is supposed to conduct.
