2.23" OLED display pHAT for Raspberry Pi
Now available from PMD Way is this gloriously wide OLED display pHAT for Raspberry Pi Zero boards, or any other Pi with a 40-way GPIO.
The pHAT is fully-assembled and ready to drop onto your Pi. However you could also mount it remotely from your Pi using your own male-female jumper wires using the inline header pins soldered to the back of the pHAT.
Display include hardware to bolt display firmly to your Pi. By default the display is set to use the SPI bus, however you can use I2C if required (see below).

Changing between SPI and I2C interface:
The display ships set to SPI bus. To change to I2C, reflow the 0 ohm resistor shown in the circle below so it shorts the I2C pad on the bottom and the middle pad in the vertical rectangle:
