4. Connector PIN-OUT

4.1. Connectors to Board:

XBUS: VSS_1 = PIN 4, 6

VDD_1 = PIN 3, 5

GND = PIN 1, 2,

SDA = PIN 12

SCL = PIN 10

INT1 = PIN 8

INT2 = PIN 11

INT3 = PIN 9

MRESET = PIN 13

I/O (K17):

PD5 = PIN 9 (I2C OUT -

Enable

alternatively)

USRBUS: ADC0 = PIN 1 (Sharp front)

ADC1 = PIN 2 (Gyro)

ADC4 = PIN 5 (Sharp Rear)

PWR = PIN 3

ADC (K18): ADC4 = PIN 3

(Sharp rear -

alternative PIN)

Hint: The signal name PD5 on the Sensor Bord was derived from the Control M32

board. PIN 9 of the I/O header on the M256 Board is labeled as PB6

(IO_PWM/T0/T1).

The signal ADC4 on the Sensor Board was derived from the Control M32

board. PIN 3 of the ADC header on the M256 Board is labeled as ADC9

(ADC_IO2/CMP).
