Microcontroller Displays & Touchscreens

Shop microcontroller displays and touchscreens for embedded electronics, development boards, single-board computers and custom control projects. Vetco Electronics carries OLED displays, character LCD modules, color LCDs, capacitive touchscreens and HDMI display modules for use with platforms including ESP32, Arduino, Raspberry Pi and other microcontroller and embedded systems.

Whether you need a compact display for sensor data, a character LCD for a control panel, or a large touchscreen for an interactive interface, these display modules provide practical ways to add text, graphics, menus, status information and touch control to an electronics project.

OLED Displays for Microcontrollers and Embedded Projects

OLED display modules are a popular choice for projects that need clear graphics and text in a compact package. Small OLED screens work well for sensor readouts, status displays, portable electronics, instrumentation, IoT devices and other embedded applications where space and power consumption matter.

Our selection includes compact monochrome OLED displays as well as specialized transparent OLED modules. Depending on the model, these displays can connect through common interfaces such as I2C or SPI, making them suitable for many ESP32, Arduino and other microcontroller projects.

Character LCD Displays with I2C

Character LCD modules remain one of the simplest ways to display text, measurements, menus and system status. Vetco carries common character display formats including 16x2 and 20x4 LCD modules, including models equipped with I2C interface boards that reduce the number of microcontroller pins required for connection.

These LCD displays are useful for test equipment, sensor projects, control panels, clocks, monitoring systems, educational projects and other applications where a straightforward text display is needed.

Touchscreen LCD Displays and Embedded User Interfaces

For projects that require both a visual display and user input, touchscreen LCD modules provide a convenient way to build interactive interfaces. Capacitive touchscreens can be used for buttons, menus, dashboards, settings screens and other graphical user interfaces without requiring a separate keypad or control panel.

Vetco carries touchscreen displays in several sizes and configurations, including compact microcontroller display modules and larger HDMI touchscreens suitable for Raspberry Pi, embedded computers and custom HMI projects.

HDMI Displays for Raspberry Pi and Embedded Computers

HDMI touchscreen displays are useful when a project needs a larger graphical interface or when the host system provides standard HDMI video output. These displays can be used with Raspberry Pi computers and other compatible embedded systems for applications including control panels, dashboards, portable systems, test equipment, kiosks and custom user interfaces.

Displays for ESP32 Development

ESP32 development boards are increasingly used in projects that combine wireless connectivity with graphical displays and touch interfaces. Many LCD, OLED and touchscreen modules can be used with ESP32 boards through interfaces such as I2C, SPI and other digital connections.

For more advanced projects, Vetco also carries ESP32 development hardware with integrated displays, including ESP32-S3 and ESP32-C6 based boards with built-in LCD, AMOLED or touchscreen interfaces. These integrated platforms can reduce wiring and make it easier to build compact IoT devices, control panels, smart displays and portable embedded systems.

Microcontroller Display Interfaces: I2C, SPI and HDMI

Choosing the right display often starts with determining which interface your project supports. Common display interfaces include:

• I2C for compact OLED displays and character LCD interface boards
• SPI for many color LCD, OLED and touchscreen modules
• HDMI for larger displays used with Raspberry Pi and other embedded computers

Before selecting a display, check the operating voltage, interface type, resolution, touch capability and software support required by your development board or host system.

Displays for Control Panels, IoT Devices and Electronics Projects

Microcontroller displays can be used in a wide range of electronics projects, including:

• IoT dashboards and connected devices
• Sensor and environmental monitoring systems
• Robotics and automation controls
• Test equipment and instrumentation
• Home automation interfaces
• Portable and battery-powered electronics
• Touchscreen control panels and HMIs
• Data logging systems
• Educational electronics projects
• Custom embedded devices
