Compatible OLED Options for SPIISD V2

  Versatility in Display Sizes...

SPIISD V2 is designed to support various display sizes, allowing for a flexible PCB layout that avoids obstructing button operation while keeping the device compact. This feature enables users to swap screens according to their preference, from a compact 0.96” OLED to a large, easily visible 2.42” OLED. Enthusiasts can even design custom 3D-printed cases to match their chosen display for a personalized touch.

  OLED (LCD) Requirements

The OLEDs used with SPIISD must meet the following specifications:

1. SPI Interface: Only OLEDs with a 7-pin SPI connection are supported (Note: 4-pin OLEDs are incompatible).
2. Resolution: 128x64 pixels.
3. Driver: The interface must use the standard SSD1306 driver.

As long as these criteria are met, most OLEDs—regardless of color—should work seamlessly with SPIISD.

  Compatible OLED Options

The OLED 7-pin socket has two rows. Normally you should only use the bottom row. Use the top row only for OLED 2.42". 

This is simply because the pinout for 2.42" is reversed. Connecting it the other way around will damage the OLED. We recommend soldering only one row.

1. 0.96” OLED

*Both of the two types of 0.96" OLEDs shown in the pics can be used.

• Overview: This is the standard display included with the SPIISD kit.
• Compatibility: Check the back of the OLED PCB to ensure the resistors and capacitors match the design in the reference photo. If they do, you can swap screens without issue.
• Features:
  • Available in various colors, including bi-color options (e.g., blue and yellow), adding a fun and colorful touch.
  • Offers excellent cost-performance balance despite its smaller display size.

2. 1.54” OLED

*Both of the two types of 1.54" OLEDs shown in the pics can be used.

• Overview: Available as an optional upgrade.
• Compatibility: Similar to the 0.96” OLED, ensure the PCB layout matches the reference photo.
• Features:
  • A larger screen that expands almost to the width of the SPIISD, delivering an impactful visual experience.

3. 2.42” OLED

• Overview: The largest compatible display, creating a bold visual statement.
• Compatibility: Ensure the PCB matches the reference photo. However, note the 7-pin connection order is reversed, requiring you to use the top side of the SPIISD’s 7-pin footprint (other OLEDs use the lower side).
• Features:
  • Dramatically larger size, though it significantly protrudes beyond the SPIISD’s PCB.

Bonus: 1.3” OLED (Not Recommended)

While the 1.3” OLED can display output, it uses a different driver (SH1106), resulting in noise and garbled text. Due to these issues, it is not recommended for SPIISD use.
