Question on Flutter Explorer board hardware

[cbell]

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.

Thanks,
Chris.

To answer my own questions:

SPI port:
1 D4
2 S9/Master In
3 S10/Clock
4 3.3V
5 GND

USB port: yes, mirror of on-board port.

Mosfet switches: the top pin (toward the servo ports) is connected to power "raw".

Top two pads (also the DC barrel and battery JST port) are DC Raw power.

Grove JST connectors have pins 1 and 2 as labelled on the silkscreen, with pin 3 3.3V, and 4 is GND.

Servo ports also connect to RAW power.
