tacbanon,
Are the remaining sensors analog or I2C, or...
Not really concern with the USB part as of now...

Sensors and modules:
Barometric - SPI
Ambient - Analog - (Done)
Temp (DS18B20) - Digital
Battery monitoring - Analog (Done)
Accelerometer - Analog
RTC - I2C (Done)
SDCard - SPI (Done)

I will try to look for an I2C accelerometer sensor if this will be easier...but it will take me another few days to get one. I have the ambient and Battery monitoring working. I also have an RTC and SDCARD on board running for data recording...
Thanks for the time helping.
