VIN: USE THIS PIN TO POWER THE SDP

REQUIRES 4-7V 200mA

VIO: USE TO SET IO VOLTAGE MAX DRAW 20mA

BOARD ID EEPROM (24LC64) MUST BE ON I2C BUS 0, ADDRESS IS AT USER DISCRETION

I2C BUS 1 IS COMMON ACROSS BOTH CONNECTORS ON SDP - PULL UP RESISTORS REQUIRED

BMODE1: PULL UP WITH A 10k RESISTOR TO SET SDP TO BOOT FROM A SPI FLASH ON THE DAUGHTER BOARD

(CONNECTED TO BLACKFIN GPIO - USE I2C_0 FIRST)

MAIN I2C BUS (CONNECTED TO BLACKFIN TWI - PULL UP RESISTORS NOT REQUIRED)
