Description
The 2.4 inch TFT Touch Screen Module with micro SD card slot is now available as a SHIELD for Arduino UNO. It has a four wire resistive touch screen, a micro SD card socket, a reset switch and a convenient Arduino Uno shield footprint.
Model: ACS44240D
Features
- Colorful, 18-bit 262,000 different shades
- Bright, 4 white LED backlight. On by default but you can connect the transistor to a digital pin for backlight control
- Works with any Arduino 328 or Mega (Leonardo not supported yet)
- Onboard 3.3V 300mA LDO regulator
- 4-wire resistive touchscreen
- Uses digital pins 5-13 and analog 0-3. That means you can use digital pins 2, 3 and analog 4 and 5. Pin 12 is available if not using the micro SD

Usage
Hardware
- STEP1 Prepare the below stuffs:
Crowduino Uno 2.4 inch TFT Touch Shield for Arduino Get one now Get one now
- STEP3 Connect Crowduino Uno to PC via a Mini USB cable.
Software
- STEP 1 Download filesArduino_Demo_code_ArduinoUNO%26Mega2560.zip
- STEP 2 Configure controller board&communication port
- On top of the Arduino IDE, click “Tools>Board>” and select “Arduino Uno”from the available options
- Select the COM port that indicates Arduino Uno. Please note that the actual numbers after the “COM” word will vary from computer to computer, so they could be different from the ones shown in the figure.
- STEP 3 Install Library: Unzip the Arduino Demo code_ArduinoUNO&Mega2560.zip file. Copy the dependent libraries in the Install libraries directory in the package (shown below) to the Libraries directory under the Arduino installation directory
- STEP6 After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs successfully
