128x32 I2C Graphic OLED Module with ZIF Connector
Part Number: CFAL12832D-B
Super popular small oled! This white-on-black OLED is perfect for display panels that have little space and need a high resolution 128x32 graphic display. With a 24.38mm x 7.58mm viewing area, this is one of the smallest OLEDs available.
- Thin form factor! 1.45mm
- Solomon Systech SSD1306 or compatible controller communicates with I2C, 3-wire SPI, or 4-wire SPI
- Only 3.3v
- Easy ZIF connection. The FPC mates with a 12-pin ZIF connector, which can be processed through your normal SMT reflow.
- Typical mating ZIF connectors can be found here: Bottom Contact and Top Contact.
The Solomon Systech SSD1306 controller needs only a single 3.3v supply for power and logic levels for communication, making it a top choice in low power or battery powered applications. The 3 wire / 4 wire SPI or I2C serial interfaces require only 12 lines. Coupled with a ZIF connection (0.50mm pitch), connecting this module to your host device is a simple task.
Do you need a carrier board to speed up your development? We have the CFA10054 OLED carrier board for this display.
This OLED display has the same connector as these other displays: 64x48 Small Graphic OLED and Small 48x64 .71inch OLED Display.
