Parallax Flip module pinout

EMHmark7

Hi,

I need to know which pins are I/Os that I can use as general purpose without interfering with other functions.
(I cannot open the Sch or trace files with my ExpressPCB)

My understanding is:
- All Pxx pins can be used as GPIO
- P31 and P30 are those used by the USB and need to be free if I wish to send/receive serial messages to the device.
- P29 and P28 can be used as GPIO if I do not use I2C modules.

Am I right on all of these?

Thanks.
Marc

P28 and 29 can be used for other I2C devices, along with the EEPROM as long as they have different address.

P26/P27 LEDs
Two user-controlled LEDs are visible through tiny holes in the board, controlled by P26
and P27. Each LED will light up when the voltage on its pin is above ~2.5 V and stay on
until the pin is below ~1.5 V. Each pin is pulled down with 65 kΩ of resistance, in order
to automatically turn the LED off when the pin isn't driven high. Keep in mind that this
pull-down resistance may affect external circuits.

There is a Schematic PDF file in the ZIP.
