|
* Has two headers on the bottom for sitting on the pi as a "hat", but they are surface mounted rather than through-hole and should not be difficult to remove.
* Like most SPI displays it only requires 7 gpio's (+ 5v & GND).

|
* Old style header is through-hole making it more difficult to work with for GBZ projects.
* Has an IPS variant for a couple bucks more. In theory has better colors and viewing angles.
