Add images for Adafruit NeoKey Trinkey, AdafruitQT_PY SAMD21 and the SAMD_GENERIC boards.

I was wondering if I could find a generic image for a board without any risk of violating someones license, but did not find one. There are thousand of so called "free" images in the web, but i do not trust that promise. I was thinking to use a blurred image of a PyBoard. Maybe like this one:

Or the same kind of blurring with a Adafruit board, if they agree.

For the generic images, how about just a picture/render of the MCU with the relevant markings on it, like SAMD21x18? Then it's easy to see at a glance which chip that generic firmware is for.

You could also keep the nice renderings you have here, but at least add the SAMD21x18 etc markings somewhere, eg on top of the MCU, or on the silk screen.

Pictures taken from real chips are hard to make. Usually the markings are not clear. From the MicroChip web pages I could take these pictures, hoping they would not complain:

Can you just render some text over the top of the mock-up PCBs that you made? Or add a silk screen with the SAMD_GENERIC_Dxxx name on the silk screen?

Or add a silk screen with the SAMD_GENERIC_Dxxx name on the silk screen?

Sure. That is easy.

Edit: Updated.

I made a different image for the SAMD51 boards, showing the larger MCU package of a SAMD51J19/J20.

That looks good now, thanks!
