mlab-modules/OLED01OLED module with SSD1306 controller, I2C interface level shifter, integrated buzzer, touchscreen, and LEDs.
OLED01 is an open-source printed circuit board by mlab-modules, from the mlab-modules/OLED01 repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 60.8 × 70.9 mm with 54 parts on 47 nets, routed with 279 tracks and 54 vias.
It is built around the TLV840EVM, TSC2007IPWG4 and MIC5504-2.5YM5-TR, with the PCA9306DP, BC817-25 and EA OLEDM128-6GGA among its other parts. Its parts include 16 resistors, 12 capacitors, 6 connectors, 5 ICs and 5 diodes. It belongs with the lEDs and displays and interfaces and adapters boards of this library.
The OLED01 is an MLAB module, designed for using OLED displays, specifically the EA OLEDM128-6GGA built around the SSD1306 controller, this module communicates using the I2C protocol. The module's design uses standard MLAB headers and an internal 12V power supply, for powering the OLED display. This module provides a solution for integrating high-contrast OLED displays into various systems.
An important feature of the OLED01 module is the integrated I2C level converter, which can operate within a 3-5V power supply and signal range. The OLED01 also incorporates a pair of LEDs and a buzzer, driven by an integrated transistor and it is equipped with a reset circuit to ensure proper clear display initialization after power-up.
The OLED01 module is designed to promote user-friendly integration and durability. Its compact form factor allows for easy placement within diverse hardware configurations, and the robust construction assures longevity. The contained OLED display delivers a resolution of 128x64 pixels with high-contrast visual output.
The OLED01 module supports 4-wire resistive touchscreens through integration with the TSC2007 touch controller. This I2C-based controller enables position and pressure detection with 12-bit resolution, low power consumption, and internal preprocessing for noise reduction. The PENIRQ output allows interrupt-based touch event detection.
This expands the module's usability for interactive user interfaces in embedded systems.
The OLED01 module's versatility allows for use in a wide range of applications:
