An earlier version of this was the first one I've had where the 680 resistor failed to keep the ILI9488 MISO signal from fouling the SD card. So I used a 2N3906 PNP transistor to gate the MISO signal with *CS. Gerbers are attached. JLCPCB shipping to the U.S. went up from about $3.30 2 weeks ago to $6.60 now. Still, 5 pcbs for under $2 each is quite a bargain compaired to what I paid a dozen years ago.
