Blue Character OLED 16x2
A 16×2 character OLED display with bright blue text on a black background. Pin-compatible with standard HD44780 LCDs but with the benefits of OLED — ultra-high contrast, wide viewing angles, low power consumption, and no backlight needed since each pixel is an individual LED.
The display works with 3V or 5V power and logic, and can be controlled with just 7 digital pins. It also has a bonus 100×16 graphic display mode and an optional SPI mode (requires soldering jumper changes).
Key Features
- 16×2 Character Display – Bright blue OLED pixels on black
- HD44780 Pin-Compatible – Same pinout as standard character LCDs
- 3V or 5V Compatible – Works with both voltage levels

Note: This OLED is not compatible with LCD shields or backpacks. Use the dedicated Character OLED library (not the standard LiquidCrystal library) and wire up the RW pin instead of grounding it. The on-board boost converter may produce a faint buzzing noise.
