    Same here (55/lenses). Have seen a uTube vid of soldering tiny SMD pins - that video is 0.65 mm SMD. With flux and the right amount of solder the resist mask puts it in place - and bridges can be fixed.

    Looking at the card backside are 6 more labelled to add to the 21 on the front edge pins. The other six: 4 are internal pins on T_3.5 and 2 are on bottom pads

    @loglow - if I'm seeing this right: The one end hits the SDIO pads on the T4 and passes over the USB Host D+/D- and those pads are all soldered through the holes taking the signals to the far end for offboard use? ...

    Yes - matching the internal T_3.6 pin count and order would make it map the same - FWIW given onboard USB connector. I got this part # from a KurtE post : ‎TPS2055AD‎ shows : 2.7V ~ 5.5V About power - OP : ...

    Those details are in the 1062 processor Ref Manual you have to get from NXP. This linked post should get you there: https://forum.pjrc.com/threads/57112-Teensy-4-0-Release?p=211849&viewfull=1#post211849

    That is correct - there are moved pins for needed function and that 100 Ohm resistor goes inline with the MCLK signal.

    The 1060 was first rev of 1062 - so 1060 is the same device as 1062. 1064 AFAIK is the same with the exception of added inbuilt FLASH, but ref docs should all be 1062 or 1060. Paul should have them on PJRC.com with...

    That looks nice. I see the USB host pin order like on T_3.6 - except 1 GND in 4 pin format not 5 that PJRC sells? There is a USB Host power $1.56 IC on the T_3.6, that was on the breakouts from PJRC and designed into...
