I’m taking inspiration from the open designs of the carrier board to make my own.
And next doubts come to my mind, hope someone can clarify them:
- USB3.0: I want to put a two entry stacked USB3.0 in the board. I have seen the next table in OEM guide:
I would like to use the Use Case #2 or #3, so I can connect two different USB3.0 ports to the connector. The Note sections says that might not be support in the Software release… That’s a definitive decision or could we have two USB3.0 supported interfaces?
If so, which Jetson TX1 pins should I use, PEX1 or SATA?
- HDMI: I have checked Carrier Board design and the OEM guide mentioned above and see that the HDMI has a filter activated with an Enable for data and clock lines.
Is there any problem if I leave it always enabled? Meaning that I do not put a FET and connect it to GND.
If that is not a good idea, in the carrier board you use a I2C expander to generate this enable signal. Could I use an Jetson TX1 pin straight to generate EN signal?
- Discharge circuit: Does TX1 module needs discharge circuitry for the different voltages?
