OLed-PCB-control

OLed-PCB-control is a custom PCB project for controlling an SSD1306 OLED display using an Arduino Nano and 3 user buttons, including an on/off latch power circuit. The project provides all necessary KiCad design files and manufacturing outputs for easy assembly and use.

Features

• SSD1306 OLED screen interface (I2C)
• 3 user input buttons
• On/off latch power circuit for energy efficiency
• Designed for Arduino Nano integration
• Easy-to-manufacture PCB (tested with JLCPCB)
• Includes schematic, PCB layout, manufacturing outputs (Gerbers, BOM), and component list such as the custom and assigned footrprints

Example Applications

• Menu navigation for embedded devices
• Educational electronics projects
• Portable or battery-powered interfaces

Hardware Details

• SSD1306 OLED Display:

  • Standard 128x64 pixel OLED panel.
  • I2C interface for easy microcontroller communication.
  • 4-pin header (VCC, GND, SCL, SDA) for simple connection to the PCB.
  • Powered directly from the board’s regulated supply.
  • Compatible with most Arduino SSD1306 libraries.

• PMOS Power Switch:

  • Power latch circuit uses a PMOS transistor for efficient on/off control of the board and display.
  • Allows the user to toggle power using a push-button.
  • Reduces power consumption by fully disconnecting supply when off.
  • PMOS footprint provided in the PCB design for easy assembly.
  • Typical part: SI2333DS or equivalent SOT-23 PMOS (refer to schematic/BOM for exact part).

• NPN Transistor Footprint:

  • Custom through-hole footprint for robust switching and control applications.
  • Used within the latch circuit for reliable logic-level operation.

• Standard Connectors:

  • Easy-to-source headers for Arduino Nano and OLED display.
  • All signal and power lines clearly labeled in silkscreen.
