Xplained Pro I2C Address List

The Table 2 lists the used I²C addresses on the Xplained Pro platform. Register an I²C address via edbg@atmel.com so that this can be added to the list which will avoid conflicts on the I²C bus. The I²C compatible device adresses in Table 2 must be shifted left to form the SLA+W or SLA+R address when transmitted over the I²C compatible interface as show in Table 1.

Table 1. Format of SLA+W and SLA+R
Bit 7	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0
I²C address e.g. 0x4A							Read/Write

Table 2. Xplained Pro I²C Address List
I²C address	Products using this address	Configuration option
0x28	All Xplained Pro MCU boards (I²C interface to the embedded debugger)	Cannot be changed permanently so each reboot of the EDBG resets this to the default address. Configuration can be done via Atmel Data Visualizer.
0x29	BNO055 Xplained Pro	Last bit is configurable by pull-up/down.
0x4A	maXTouch Xplained Pro (mXT112S touchscreen controller)	Not configurable
0x4B	ATMEGA256RFR2 Xplained Pro (temp. sensor)	Last three bits can be configured by soldering. This will also change the last three bits of the EEPROM address on this board because both are within the same device.
0x4F	I/O1 Xplained Pro (temp. sensor)	Last three bits can be configured by soldering. This will also change the last three bits of the EEPROM address on this board because both are within the same device.
0x50	SAM L22 Xplained Pro (ATAES132A crypto device)	Default device address. Can be changed in internal config register.
0x53	ATMEGA256RFR2 Xplained Pro (EEPROM)	Last three bits can be configured by soldering. This will also change the last three bits of the temp sensor address on this board because both are within the same device.
0x57	I/O1 Xplained Pro (EEPROM)	Last three bits can be configured by soldering. This will also change the last three bits of the temp sensor address on this board because both are within the same device.
0x70	SHTC1 Xplained Pro	Not configurable
