Here's a test board for testing all my display libraries with all CPU's without dealing with wires, it has all popular display pinouts and can carry on arduino NANO, all Teensy's 3.x and LC, Arduino DUE, ESP8266 nodemcu 0.9, ESP8266 nodemcu 1.0, Spark core.
The Arduino Nano has a level converter and I have 2 buffers for testing SPI isolation with other SPI devices
