Is there a published schematic of the Explorer board yet?
I found a reference for the majority of the ports being Seed Grove connectors, but I still have some questions...
The SPI port has 5 pins? what are they?
Is the USB port a mirror of the on-board port, so should be one or the other, not both?
the three "High current Mosfet switches"? pinout? access: they share the D4/D5 lines with the grove connector, will they fight?
There are two pads near the servo connectors labelled +-, are they power? Which bus: battery, DC, Vcc?
I guess I could get out the ohmmeter and check tomorrow.
