low height board like the Adafruit Proto Under Plate PiCowBell for Pico

Hi for the Pico Adafruit has a low height board : Adafruit Proto Under Plate PiCowBell for Pico - Reset Button & STEMMA QT.

Is there something like that for the teensy 4.0? (The pico board seems 2.54 mm wider.)? Even with screw terminals?
 
Nice idea, wouldn't be hard to do something similar for T4. Slightly more permanent than a small breadboard.
 
And if there are terminal blocks or a number of jst connectors available, it could be a permanent solution.

BTW. This board has the disadvantage that there are no holes on the outside(only inside). Soldering on a board is a less stressful than on a microcontroller board.

Adafruit designed a Teensy to Feather adapter that will work (mostly) with the Teensy 4.0. With the longer Teensy 4.1, you need to raise the Teensy up so it clears the JST battery port, or mount the Teensy underneath (the outer ports use the feather wing pin out, not the Teensy pin out):
The mostly part comes from some differences between the Teensy 3.2 and 4.0:
  • The Teensy 4.0 does not have an analog reference pin (AREF). Instead join the 3.3v power to the AREF hole on the feather adapter.
  • The Teensy 4.0 does not have the A12/DAC pin, instead that pin is the on/off pin. This means featherwings that use the first analog pin (i.e. A12/DAC on the Teensy 3.2) will not work. If you use a featherwing that wants to use the analog pin, you would need to wire in an unused analog pin.
  • Note, the reset button on the featherwing boards is really the program button on the Teensy. Perhaps wire the on/off pin to the reset/program pin, or perhaps keep the program button connected.
  • The Teensy 4.0 does put out A11/A12 in the location the Teensy 3.2 did. Given none of the feather wings use A11/A12, you don't have to connect it.
It is probably bigger than you want, but I like the Adafruit mint tin prototype (perma-proto) board that is big enough for either the Teensy 4.0 or 4.1. Or get the mini-mint prototype board that is just long enough for a Teensy 4.0 (possibly solder female headers or stacking headers if you don't want to permanently solder the Teensy to the board). The quarter sized perma proto board is also Teensy 4.0 sized:
It isn't a pin output board, but if you just wanted to add QWIIC connectors, Sparkfun makes a board for the Teensy 4.0 (and another one for the 4.1):
The company protosupplies.com has some Teensy 4.0/4.1 configurations, including a low profile Teensy 4.0:
When I've bought Teensy 4.1's in the past, I would go with protosupplies, since they offer versions with the PSram and flash memory cards pre-soldered on:
 
I'm specially interested in a low profile one and available in EU.

I have normal height versions, I think actually for the arduino nano.
