Just noticed those two LEDs on the less populated surface showing in the 3rd picture above might interfere with the SD card if their height is too high. It's not an issue for the one on the other side because the connector faces the other way towards the P2, so you may not have noticed this in the design. If you find you need a re-spin for any reason maybe rotate and move them down to under the USB socket, or spread one either side of the SD sockets if there is room perhaps... there's probably space to run the extra traces.

SD cards and LEDs have various height choices.
You can also get right angle LEDs, and those can avoid the SD card covering the main LED light of a vertical LED.
I like these ones, bright, and a good price, and not too small... - you can do a PCB design that takes a selection (vert or right angle) , just get the right angle ones right https://lcsc.com/search?q=LTST-S220

Peter, which pins are available in the 40-pin DIP adapter, and what is the spacing between the 2 rows of pins? Will you sell a de-populated version of the P2D2 that just has the P2, crystal, voltage regulators and flash?
