Key benefits Enables use of a 3.3V TFT display on standard Arduino-style boards by providing the required interface and level adaptation. Lets projects use both touchscreen input and SD card storage when paired with a Mega2560 (or the TFT01 Mega Shield V2.2), removing pin conflicts common on smaller boards. Improves display stability through an IC voltage-division scheme designed for the TFT01 module. What this product does The TFT01 LCD itself operates at 3.3V and cannot be connected directly to a standard 5V board. The dedicated TFT Shield (designed section) is used to adapt and connect the TFT01 LCD to a standard board safely and reliably. TFT01LCD supports an 8-bit interface mode that allows the SD card interface and the touchscreen interface to be used simultaneously while providing voltage division inside the interface IC for more stable display operation. The TFT01 Mega Shield V2.2 is built for 3.2 inch TFT LCD modules and supports a 16-bit communication mode. When used with an Arduino Mega board, the shield takes advantage of the Mega’s extra I/O so both the SD card and touch functions can operate at the same time without pin conflicts. Compatibility and important attributes Voltage: TFT01 LCD requires 3.3V operation; shield provides the correct interfacing for use on standard boards. Board compatibility: Best used with Mega2560-class boards or the TFT01 Mega Shield V2.2 to access simultaneous SD and touchscreen functions. On smaller boards such as Face 328S, only one of the touchscreen or SD interfaces can be used at the same time due to limited I/O. Size: Designed for 3.2 inch TFT LCD modules (compatible with the TFT01 Mega Shield V2.2). Interface modes: Supports 8-bit mode (TFT01LCD) for concurrent SD + touch usage and 16-bit mode support on the Mega Shield for improved throughput when paired with a Mega board. Stability: Uses IC voltage division for improved display stability when interfacing between 3.3V LCD and host board. Practical applications Touch-based control panels: Build a 3.2" touchscreen interface for equipment or appliances using an Arduino Mega and the TFT01 Mega Shield V2.2 to run UI and log data to an SD card. Data-logging display: Create a field data logger that displays real-time readings on the TFT while saving logs to an SD card; use the 8-bit TFT01LCD setup for simultaneous touch input and SD storage. Educational and prototyping projects: Rapidly prototype interactive projects on Mega2560 platforms that need a responsive 3.2" display with both touch input and removable storage. What to expect in a setup Use the TFT Shield (designed section) to connect the 3.3V TFT01 LCD to standard Arduino-style boards. For full simultaneous functionality (touch + SD) use a Mega2560-class board or the TFT01 Mega Shield V2.2; on Face 328S only one interface (touch or SD) will be available at a time. Choose 8-bit mode (TFT01LCD) when you need both interfaces simultaneously, or 16-bit mode on the Mega Shield when you need higher data throughput with a Mega board.
