Temperature Sensor

The ATSAMR30M Sensor Board has an on-board digital temperature sensor (AT30TSE758A). This sensor is interfaced with the ATSAMR30M through I2C bus and is available on I2C slave address 0x48 (7-bit MSb address). The AT30TSE758A also has a serial EEPROM, which is accessible through the same I2C bus with the slave address as 0x50 (7-bit MSb address).
