The High-Current Driver area of the BOT40 Controller Board is very versatile, and can accommodate both NPN and PNP bipolar transistors, as well as both n-channel and p-channel MOSFETs. Driver power can be supplied either from the BOT40 +5v buss [jumper J10], or from an external source [Jumper J11 to +S buss]. The pcb contains 3 identical driver layouts. Heavy pcb traces can carry up to 5 Amp.

The following diagram shows the different ways this area can be wired up:

The last circuit, the P-MOSFET pullup driver, is especially useful for switching on-off power to large external 5v loads.
