Developer Kit Feature Considerations

3.3 TI TXB0108 Level Shifters
The P3449 carrier board uses these level shifters to shift many of the signals going to the 40-
pin header from 1.8V to 3.3V. The design of these level shifters supports bidirectional signaling
without the use of a direction signal but has some side effects that should be considered. See
the
Jetson Nano Developer Kit 40-Pin Expansion Header GPIO Usage Considerations
Applications Note
for details.
3.4 Features Not to be Implemented
The Jetson Nano Developer Kit carrier board features that should not be copied as they are
not required or useful for a custom carrier board design. The ID EEPROM (P3449 - U11) is a
feature that is used for NVIDIA internal purposes, but not useful on a custom design. A similar
function may be desired for a custom design, but the NVIDIA software will not interact with
these devices and the I2C address used by the developer kit carrier board ID EEPROM on the
I2C2 interface (7’h57) should be avoided.
