Teensy 4.0 - footprint for use of USBHost pins

Development Boards Teensy
1

I am working in Eagle and want to use the Teensy 4.0 with USB Host capabilities.

My plan is to use the Teensy 4.0 footprint from the library at GitHub - eagleman1022/Eagle-Library-Teensy: This repository holds the Eagle Cad library for the Teensy 3.6 and newer. There may be more than one version of each device to better facilitate varying usage. · GitHub and delete the pins I am not using (leaving only the 14 pins on each side and the pins for USB Host D+ and D-).

Here are my questions:

  • Can someone confirm that the D+ and D- pins in the footprint in Eagleman’s library file are placed appropriately for pogo pin connection to the D+ and D- pads on the Teensy 4.0?

  • Is the spacing between the D+ and D- pads 1.8 mm?

  • Is the location and dimensions of the D+ and D- pads documented anywhere on the PJRC or sparkfun pages?

  • Can anyone identify the pogo pins this footprint was designed for? The drill seems just a little small for the Mill Max pogos I looked at.

Thanks for any help anyone can provide.

There’s some spacing info here Teensy Dimension and Size and you can use the 4.0 files here too Eagle CAD libraries for use with Teensy USB development boards - the pad sizes and such are viewable in the pcb file; D+/- are listed here as well

As for the eagleman-specific questions you might have more luck posting the PJRC forum Teensy Forum or comparing them with the others above
