SMD pads for 4.1 are not listed #38

Open mrwm opened 2 years ago

mrwm commented 2 years ago

The SMD pads listed at the back of the teensy 4.1 isn't included in the library (nor the footprint). Is it possible to include it here?

Those pads are designed for SMT parts to be placed on the teensy.

What kind of connector and footprint would you expect on a baseboard to connect to those pins?

mrwm commented 2 years ago

I was looking to breakout extra SMD pins in the back for I/O as such:

The footprint should be something similar to the ESP-PSRAM32 (which I have pictured above).

An example of such usage can be found with this teensy project that aims to decode laptop keyboard pinouts.

Thanks. I understand how having connections to those pins might be useful, but I'm not sure what connectors could be used on each side to make a reliable connection. Do you have some in mind?

mrwm commented 2 years ago

As for the footprint, I would assume that it would be ideal to have through hole connectors. With size constrains, leaving them as SMD PSRAM pads would work as well.
