A 2.2″ TFT LCD breakout with 320 × 240 resolution and full 18-bit colour (262,144 shades), driven by an ILI9340 (or compatible) controller over 4-wire SPI. The onboard frame buffer means even low-memory microcontrollers can drive this display without issues.
The breakout includes an ultra-low-dropout 3.3 V regulator and a 3 V / 5 V level shifter, so it works with both 3.3 V and 5 V logic. A microSD card slot on the board lets you load full-colour bitmaps from a FAT16/FAT32 formatted card.
Key Features
- 320 × 240 TFT Display – Bright, vivid colour with fast refresh rates
- 18-Bit Colour – 262,144 shades for rich, detailed graphics
- ILI9340 Driver – Consistent driver chip across all units for reliable code compatibility
- 4-Wire SPI Interface – Works with any microcontroller; hardware SPI recommended for best performance
- 3.3 V / 5 V Compatible – Onboard regulator and level shifter
- MicroSD Card Slot – Load bitmaps directly from a FAT16/FAT32 card (card not included)
Ideal For
- Adding a colour display to Arduino and microcontroller projects
- Displaying sensor data, menus, and status information
- Showing bitmap images loaded from microSD
- Portable and embedded display applications
Package Contents
- 1× 2.2″ 18-Bit Colour TFT LCD Breakout with MicroSD Slot
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- frame buffer
- A frame buffer is memory that stores a complete image before it is shown on a display. Displays without their own frame buffer need the controller to continuously send pixel data, which affects the choice of microcontroller and software library.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
