Are the Jetson module A02 and B01 incompatible?

I have a jetson nano developer board 945-13450-0000-000.
In addition, a custom board was manufactured by referring to the B01 version circuit diagram.
if you operate this custom board with jetson module on the developer board, the HDMI output and Ethernet will not work.
The Jetson module knows that there is a difference between version A02 and version B01.
Is this because of the A02 version of the jetson module on 945-13450-0000-000?

And,
What’s the difference between Jetson module on developer board (945-13450-0000-100) and production module (900-13448-0020-000)?
Are there any differences besides SD card and eMMC?
Are the two modules compatible?

Hi kimgon,

Yes, they’re different, the board design file is for B01 module, it’s not compatible with A02 module.
The pinout differs between B01 modules and A02 devkit module.

Hi, kayccc

Is the HDMI output and Ethernet not working due to different pinout?

Please reply again to the question below.
What’s the difference between Jetson module on New developer board B01(945-13450-0000-100) and production jetson module (900-13448-0020-000)?
Are there any differences besides SD card and eMMC?
And is it compatible between these modules?

That could be, we didn’t do that test by using A02 module on the carrier board of 945-13450-0000-100.

Except the SD card and eMMC, the Jetson production modules are suitable for deployment in a production environment throughout their operating lifetime, thus some components are difference for lifetime purpose, but design is the same.

The 945-13450-0000-100 (B01) is the Jetson Nano Developer Kit which adds support for production Jetson Nano module and replaces 945-13450-0000-000 (A02).
Version B01 and version A02 are not compatible, no matter on Jetson Nano module or carrier boards.
