I am thinking of trying out JLC SMT assembly service and I am looking for ideas on what to add to a general purpose board the Teensy would plug into. 3.3v regulator powered from the usb 5v on the Teensy pin, a few rail to rail op amps with jumper selectable gain, I2c OLED display, and some stemmaQT connectors are on the list. Any ideas on what you would want to have if you were making one to make solderless breadboard projects faster to prototype? The board can be up to 100 mm sq for the same price if it stays 2 layers so I have some room to play with. Would header with the spi connections and a few cs lines be a must have for you? Are the boards with a ground, Vcc, for each i/o useful?
Any suggestions welcome. Kicad project files will go up on a public gethub if I get a version I like.
