1 PNP transistor instead of 2 NPN #10

If the purpose of two transistor is to light the led when SELECT is down, you could just use a PNP transitor as shown here. image

Hi, yes thanks I know. I chose two NPN because that was what I had at home at the time and they are small and cheap. Feel free to change to a PNP if you want to. If I do a new revision maybe I will change to a PNP and also change the Plug to a edge connector, like SukkoPera's version here https://github.com/jbilander/sdbox/issues/2#issuecomment-767763618.
