Our 2.7 inch range currently covers 5 part numbers at 128x64, driven by SSD1322 (SSD1325 on one build) over MCU / SPI and parallel, in green, blue, white or yellow, 16 grey scales. It is the largest monochrome graphic size in the range, with 16 grey scales for readable icons and waveforms.

Mechanical details
The standard build measures 73.0 x 41.86 x 2.0 mm with an active area of 61.41 x 30.69 mm, which is the number you need for the bezel cut-out. Panel thickness stays around 1.2 to 1.4 mm for the monochrome builds, so the module sits almost flush behind the cover window.
Interface and driver
These modules run on the SSD1322 (SSD1325 on one build), and the interface options are MCU / SPI and parallel. On the I2C builds only four pins are needed (VCC, GND, SCL, SDA), which is why this size is common in Arduino, ESP32 and STM32 projects as well as in production hardware. The parallel builds suit hosts that already drive a character display and need a drop-in upgrade.
Where this size fits
Typical uses are industrial HMI panels, benchtop instruments, medical devices and control consoles. Choose the 1.5 inch version if space is tighter.
What resolution does the 2.7 inch size come in?
The standard build is 128x64. Portrait and alternative formats are listed in the table above.
Can I run this size from an Arduino or ESP32?
Yes. Choose an I2C part number and the wiring is four pins; libraries for SSD1306, SH1106 and SH1107 are widely available. SPI builds give a faster refresh for animation but need two more pins.
Is a wide temperature version available?
Selected part numbers in this size are built for -40 °C to +80 °C operation. Tell us the ambient range your product has to survive and we will confirm which builds are qualified for it.
What can be customised?
On this size we regularly adjust the FPC length and pinout, the connector type, the cover glass and the adapter PCB. Changes to the glass itself need tooling, so they only make sense at volume - we will say so honestly rather than quote an unrealistic MOQ.
Custom builds and samples
As a China based display company and module supplier, we hold stock of the standard part numbers on this page and ship samples in one to two weeks. Send your size, resolution, interface and temperature requirements and we will confirm feasibility with a drawing within one working day.
