All you need to get started with the Photon OLED Shield is a Photon, a

micro-USB cable, and the OLED shield. You’ll also want to sign up for an

account on particle.io and register your photon. Instructions on how to do

this can be found at docs.particle.io.

Suggested Reading

• Serial Peripheral Interface (SPI) – SPI is the preferred method of

communication with the display.

• I C – Alternatively, I C can be used to control the display. It uses less

wires, but is quite a bit slower.

OLED Shield Overview

Pin Descriptions

Since the shield does all of the work for you, there’s no need to actually

wire these connections - but in case you’re looking at datasheets, or code

for the Microview or OLED breakout, this table will give you a clue as to

what the shield is doing. As always, you can check the schematic for more

info.
