DESCRIPTION
J1
The J1 is used to select which sensor will be connected to the SAMG55 master I2C. Only two jumper shunts
are allowed.
Jumper shunts on pin-1/2 and 3/4: IMU Sensor primary I2C is connected to SAMG55 I2C master
Jumper shunts on pin-5/6 and 7/8: Other Sensor I2C is connected to SAMG55 I2C master. In this
configuration TDK IMU Sensor is connected to SAMG55 SPI master.
J2
The J2 is for board power source selection. Only one jumper shunt is allowed.
Jumper shunt on pin-1/2: board power is from EDBG USB on J500
Jumper shunt on pin-3/4: board power is from FTDI USB on CN6
Jumper shunt on pin-5/6: board power is from SAMG55 USB on J30
J3
J3 is for system VDDIO level selection.
Jumper shunts on pin-1/2: VDDIO=3V3
Jumper shunts on pin-3/2: VDDIO=1V8
Jumper shunts on pin-4/2: VDDIO=1V2
J4
J4 have digital signals as test points.
Pin-1: SPI /CS
Pin-2: SPI SCLK, I2C SCL
Pin-3: SPI MOSI, I2C SDA
Pin-4: SPI MISO, I2C AD0
Pin-5: INT1
Pin-6: INT2
