Two rows by sixteen characters. OLED blue character color.
The character display attached to each of the six modules in the product line contains two rows, each consisting of sixteen characters. Thus, the total character count for the image displayed can be a maximum of 32. Three built-in font tables are included in every module allowing for any standard A–Z / 0–9 character as well as many symbols. These characters illuminate in the same popular blue color of our other OLED displays.

When it comes to interface options, the 2x16 Modular OLED product line has three main interfaces available to choose from.
Parallel – This type of interfacing is a well-known and common interface. Any developer has probably worked with this interface before and utilized its quick-to-send batch style commands. However, this does tie up more pins to connect than other interface options.
SPI – Also known as "Serial Peripheral Interface", this method requires less than half the pins needed for connection by parallel interface and sends its commands to and from the display in series.
I²C – "Inter-Integrated Circuit" is also a serial interface, but utilizes a format of "master" and "slaves" with the devices it interfaces with. This option makes it easier to talk with many devices as the commands sent from the "master" can be addressed to a specific device (or "slave") and the other devices can ignore that specific command.

Connection Port Options
The cornerstone of the 2x16 Modular OLEDs are the great connection port choices that come alongside the interface options.
2x18 Female Pin Header
This is the connection port used with the parallel interface option. It requires the highest number of pins to connect with, but is a long-time standard in the industry.
2x8 Female Pin Header
One connection port is used for either serial interfaces. With this connector, you save more pins than with parallel and can interface to your display via SPI or I²C.
RJ45 (Ethernet CAT Cable)
This connection port is paired with SPI interfacing and is very easy and convenient to connect with. It is a much simpler connection than a typical pin header with ribbon cable. The RJ45 cable compatibility also allows for much longer cables to be used when connecting.
1x8 / 1x7 Through-Hole
This connection option is designed specifically for Arduino users. The single row through-hole pin out makes pairing the OLED and Arduino board a breeze. The 1x8 is for SPI, and the 1x7 for I²C interfaces.
