2.4" Arduino Lcd Shield

2.4 inch 320x240 Arduino TFT Lcd Shield + Resistive Touch + MicroSD Socket

Reset Button 18bit 262K Color 2.4” TFT Graphic Display Mega 2560

     The 2.4" TFT LCD Module Shield combines a 2.4 inch diagonal, 320x240 pixel, 18 bit (262K) color TFT display and a 4 wire resistive touch panel on a single board. The board has the Uno pin layout: it plugs directly on top of the controller board, no cables or soldering needed. The display is driven over an 8 bit parallel data bus, so it draws faster than SPI displays; the backlight is white LED.

     There is a micro SD card slot on the edge of the board; pictures, fonts or log files can be read from the card and shown on the screen. The board has a reset button and a 3.3V regulator, and it can be used with 5V control signals. The resistive touch surface is used with the included stylus or with a finger.

     The product is in a sealed bag. We open every unit, test it with the graphictest_kbv example of the MCUFRIEND_kbv library and check that it works before shipping. It suits thermostat, incubator and greenhouse control screens, touch menus, weather station displays and simple games.

Key features:

     Color touch display on one board: A 4 wire resistive touch panel sits on top of the 2.4 inch 320x240 pixel TFT display; buttons drawn on the screen are pressed with the stylus or a finger, no separate keypad needed.

     Plug in and use: The shield in Uno pin layout sits directly on the controller board; no jumper wires, soldering or breadboard needed.

     Fast 8 bit parallel drawing: The display is driven over an 8 bit parallel data bus; full screen fills, graphics and menu changes are faster than on SPI displays.

     Micro SD card slot: Pictures on a micro SD card inserted in the on board slot can be shown on the screen, and measurement logs can be written to the card.

     Tested before shipping: Every display is run with the graphictest_kbv example and checked before it is shipped.

Features:

• Product type: 2.4" TFT LCD touch display shield (Uno pin layout)
• Display size: 2.4 inch (diagonal)
• Resolution: 320x240 pixels
• Color depth: 18 bit (262K colors); the library drives it in 16 bit (65K colors) mode
• Touch: 4 wire resistive; used with stylus or finger
• Display interface: 8 bit parallel data bus and control lines
• Driver IC: may vary by production batch (such as ILI9341, SPFD5408); the MCUFRIEND_kbv library reads the ID and detects it automatically
• Test: works with the MCUFRIEND_kbv graphictest_kbv example
• Memory card: micro SD card slot (SPI)
• Reset button: on board
• Backlight: white LED
• Supply and logic level: 5V (from the shield pins), 3.3V regulator on board; can be used with 5V control signals
• Compatible boards: Arduino Uno and Arduino Mega 2560 (Uno shield pin layout)
• Libraries: MCUFRIEND_kbv, Adafruit GFX, Adafruit TouchScreen
• Material and color: red printed circuit board, glass TFT panel with resistive touch film on top
• Dimensions: approx. 72mm x 53mm
• Weight: approx. 30gr

Usage information:

• With the controller board powered off, align the pin rows and plug the shield on top; check that all pins sit in the sockets and none is shifted.
• For the first test upload the graphictest_kbv example from the MCUFRIEND_kbv library; the driver ID of the display is printed to the serial monitor and color, text and drawing tests appear on the screen.
• Before using the touch screen run the touch calibration example of the library; write the corner values it gives into your own program.
• Format the micro SD card as FAT32 and insert it in the slot; picture files can be read from the card and shown on the screen.

Areas of use:

•  Thermostat and temperature control screen
•  Incubator control and settings screen
•  Greenhouse and aquarium monitoring panel (temperature, humidity, water level)
•  Weather station display
•  Touch menu and settings screen
•  Touch keypad for a code lock
•  Clock, calendar and timer display
•  Simple game and drawing applications
•  Graphic display of sensor data
•  Showing pictures from a micro SD card
   

Precautions:

•  The product is in a sealed bag. We open the product, test it and check that it works before shipping. In case of a return the product must be in working condition.
•  The shield uses most of the digital and analog pins of the controller board; check for pin conflicts before stacking another shield or a module that uses these pins.
•  On the Arduino Mega 2560 the micro SD slot stays wired to pins 10-13, while the Mega's hardware SPI pins are 50-53; on the Mega the SD card is used with software SPI (SdFat) or jumper wires. The display part also works on the Mega with MCUFRIEND_kbv.
•  The driver IC may vary by production batch; if the screen stays white, first read the driver ID with graphictest_kbv and use the library accordingly.
•  Do not press the resistive touch surface with sharp or hard objects; use the included stylus. The glass panel breaks if it is hit.
•  When plugging in the shield, check that its underside does not touch the USB socket of the controller board; if it does, put insulating tape in between.

Package contents:
