Myterious I2C devices in Jetson Nano 2GB

mysterious I2C device

Typing the command “sudo i2cdetect -y -r 2” I see two mysterious I2C devices at address 0x50 and 0x57. What kind of devices are they?

I am using a Jetson Nano 2GB.

They are eeprom and others.

Thank you for the answer.

I know, it is not important, but I am interested in the GPIO 40 pin header and in particular in the I2C busses (I am using an AD-converter, DA-converter and compass on I2C bus 0 and 1). May be someone knows a bit more details about the devices 0x50 and 0x57 on I2C bus 2? I would like to look at the datasheets.

I would also like more details about the PWM capabilities of the Jetson Nano 2GB. I can do simple PWM in Python with GPIO.PWM, but I want to understand the PWM device (4 channel frequency divider) better in order to program or set it directly . (This is another topic.)

Both are eeprom, AT24C02D-MAHM-T, as you can see in the P3449 schematic in DLC. For more pin info, you can read the technical reference manual in DLC.

Thank you, my question was answered to100%.
