2.8 inch TFT Touch Shield v2.0
TFT Touch Shield V2.0 is a resistive touch screen, compatible with Arduino/Seeeduino/Arduino Mega/SAMD21 platforms. It can be used as display device or sketch pad. Compared with the previous version, 2.8''TFT Touch Shield V1.0, we upgraded the screen driver to a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version are needed for modification before being transplanted to the new version. With a SD card module integrated on this shield, this shield reserves capability for other expansions of your project.
- Big screen with easy and comfortable experience
- Backlight controllable via programming
- 65k rich colors display
- SPI pin-saving communication method
- Full screen touch active range
|Working Voltage||5 V|
|Resolution||320 x 240|
The 2.8 inch TFT Touch Shield v2.0 is tested and fully compatible with following boards:
- Arduino Uno(all revisions)/Seeeduino(V4&V4.2)
- Arduino Mega/Seeeduino Mega
- Arduino Zero(M0)/Seeeduino Lorawan
- Arduino Leonardo/Seeeduino Lite
- Seeeduino Cortex-M0+/Seeeduino Lotus Cortex-M0+
The boards are not listed above mean that it might have chance to work with the platform board however requires extra work such as jump wires or rewriting the code. If you are interested in digging more, welcome to contact email@example.com.

You can use the NOT USED pins to control the others module.
This getting started is based on Win10 and Arduino IDE 1.6.9 environment.

Download Arduino Library¶
This library supports below platforms:
- Arduino/Genuino UNO
- Seeeduino V¾.0/4.2
- Arduino/Genuino Mega
- Arduino Leonardo
- Seeeduino Lite/Clio/Lotus
- LinkIt ONE(Touch panel does not work)
Click to download the Touch Screen Driver，then please click on below button to download the library and install it, if you don't know how to install an Arduino library, please refer to the tutorial (HOW TO INSTALL AN ARDUINO LIBRARY).
This library includes below examples,
We use example 'shapes' for this demo.
Connect the cables and Upload the code¶
Step1. Insert the TFT_Touch_Shield_V2 board to Seeeduino,
Step2. Connect your Seeeduino board to computer with USB cable
Step3. Open Arduino IDE, Select the correct COM port and Boards(in this example we use Seeeduino V4)
Step4. Click on File > Examples > TFT_Touch_Shield_V2-master > shapes to open the code. Upload the example to Seeeduino. If you have any question about how to upload the code, please refer here for more details.
The backlight is always default on, if you want to change the backlight, you need to do some hacking on the board. Please look at the back side of the board. There's a BACKLIGHT label. One side is named as ON, and the other side is named D7. We need to cut the wire between middle pad and ON pad, solder middle pad with D7 pad. As shown below.
Then you can control the backlight via D7.
To open backlight: digitalWrite(7, HIGH);
To close backlight: digitaWrite(7, LOW);
Please be careful when use a box cutter and soldering iron.
