Adafruit Blue Character OLED 16x2

When you need low power, ultra-high contrast, and any-angle readability, these character OLED displays are unbeatable. They offer 16 characters wide and 2 rows of bright blue OLED text on a striking black background, perfect for clear communication in any light setting.

The OLEDs use a pin and shape setup compatible with 'standard' HD44780 LCDs, simplifying upgrades. Although the code differs slightly, our Arduino library ensures seamless performance with these displays, enhancing their timing sensitivity and functionality.

Take advantage of their simple operation, requiring no backlight or contrast control, and enjoy the ease of connecting via the 0.1" pitch, single-row connection port, making wiring straightforward. Each pixel is an independent LED, eliminating external backlight requirements.

Control this module with only 7 digital lines, utilizing any available analog or digital pins. The built-in character set supports English, Japanese, Western European, and Russian text, with the capability to create up to 8 extra characters. This enhances custom glyphs or foreign language support, detailed in the WS0010 datasheet.

Compatible with 3V or 5V power and logic, the display can also convert into a 100x16 graphic display. For advanced users, this versatility provides enhanced functionality by switching to 'SPI' mode via the jumpers on the PCB’s back, requiring some soldering skills.

Despite a slight squeaking noise from the onboard boost converter when in use, this OLED remains a favorite among developers leveraging its adaptability in diverse applications.
