Board size: 28 x 28 mm
Effective display surface: 11 x 23 mm
Visual Angle: > 160 °
Input Voltage: 3.3 V ~ 6 V
Wide voltage support: 3.3 V, 5 V
Viewing angle: > 160

I²C:
Signals: SCL, SDA
I²C address: 0x78 (or 0x3c, default) or 0x7a (or 0x3d).
Note: I²C addresses can (unfortunately) be specified in two ways: including R/W bit or not. Therefore 0x78 (0x7a) including the R/W bit is equal to 0x3c (0x3d) without the R/W bit
