I2C (I²C) LCD and OLED Display Modules
Two wires - SDA and SCL - shared with any other I²C devices on the same bus. It is the lowest pin count of any display interface we offer, at the cost of the lowest bandwidth.
Only 3 I²C models are published with a full specification so far - I²C is a standard interface option across the categories linked below, and we develop around 120 new models a year. Send your size and resolution rather than assuming it is not available.
Best fit
Best for extremely pin-constrained designs driving a small monochrome or OLED panel at modest resolution - status icons, short text fields, simple graphs. It matches naturally with our OLED and COG lines, which are mostly small and low-power by design.
Published I²C models
| Model | Size | Resolution | Category | Brightness | Touch |
|---|---|---|---|---|---|
| JM-PO150 | 1.54" | 128×64 | oled display module | - | - |
| JM-PO122-00 | 0.96" | 128×64 | oled display module | - | - |
| JM-PO136 | 0.96" | 128×64 | oled display module | - | - |
When I²C is not the right choice
Not suitable for colour TFT motion graphics or anything that needs to redraw quickly - I²C's bandwidth ceiling is well below SPI's, let alone RGB or MIPI. If the panel needs to animate, choose a faster interface even at a smaller size.

I²C - questions
How many published I²C models do you have right now?
3 on the site today, both small OLED panels - I²C is a common option across our OLED and character/COG lines where the resolution is modest enough for the bus to keep up.
Can I put an I²C display on the same bus as other sensors?
Yes, that is the usual reason to choose it - confirm the display's I²C address does not clash with anything else already on the bus, and that your pull-up resistors suit the combined bus capacitance.
Is I²C fast enough for a changing graph or waveform?
For a slow-moving value, yes. For anything that needs to redraw many times a second, no - move to SPI or a wider interface at that point rather than fighting I²C's bandwidth ceiling.
