Available lots of places online...
Has worked for me, replacement for Adafruit module, minus V_in and reset pins.
All libraries and code that I've tried have worked seamlessly.
Adafruit Specs:
PCB: 20mm x 35mm (0.8" x 1.4")
Display area: 7mm x 25mm
Thickness: 4mm
Diagonal Screen Size：0.91"
Number of Pixels：128 × 32
Color Depth：Monochrome (White)
Module Construction：COG
Module Size (mm)：46.30× 11.50 × 1.45
Panel Size (mm)：30.00 × 11.50 × 1.45
Active Area (mm)：22.384 × 5.584
Pixel Pitch (mm)：0.175 × 0.175
Pixel Size (mm)：0.159 × 0.159
Duty：1/32
Brightness ( cd/m2)：150 (Typ) @ 7.25V
Per Adafruit page, works with either 3.3v or 5v logic levels.
Current draw depends on how many pixels are lit. Nominally about 15ma for average usage.
I2C interface with 7-bit address 0x3C

1.54" generic, 128 x 64 px:
- I bought from Amazon, MELIFE brand, ARMv7 CPU, ASIN: B0CHF7LHVT
- SSD 1309 driver
- current draw (full screen lit): = 0.8w (at 3.3v == 240ma
- "SSD1306 embedded driver" ??
- no fonts programmed
