Product Details Note: Raspberry Pi is not included. Introduction This dual-use ABS case is designed for a 3.5-inch screen kit, suitable for Raspberry Pi 4 Model B. It’s easy to install the case with the screen and Raspberry Pi. When using the Raspberry Pi with a 3.5-inch screen, please remove the cover of the case. For usage with a cooling fan, do not remove the cover. Note: The 3.5-inch screen and cooling fan cannot be used simultaneously. If the Raspberry Pi is equipped with GPIO display drivers, the HDMI port will have no signal output. Specifications Colour: Black Material: ABS Plastic Size: 90 x 61 x 35 mm Applicable to: Raspberry Pi 4B Compatibility: Supports 3.5-inch touch screen or a fan, but not both simultaneously. 3.5-Inch Touch Screen Features Physical resolution: 320 x 480, with resistive touch control. Supports refresh rate around 50Hz for smooth video and gaming experience. Supports FBCP software drive for dual-screen display and adjustable resolution software zoom. Compatible with Raspberry Pi ZeroW, A, A+, B, B+, 2B, 3B, 3B+, and 4B. Supports Raspbian/Ubuntu/Kali system and provides driver and image resources. Note: Please connect the screen to Raspberry Pi's GPIO pins correctly to prevent damage to the touch function. How to Use the Touch LCD Connect the LCD to Raspberry Pi, insert the system SD card, connect Ethernet, and power it on. Open terminal (SSH), and install the driver on Raspberry Pi with the following commands: sudo rm -rf LCD-show git clone https://github.com/goodtft/LCD-show.git chmod -R 755 LCD-show cd LCD-show/ sudo ./MHS35-show After executing the commands, the system will restart and function normally. If equipped with GPIO display drivers like MPI2411, MPI2418, MPI2801, MPI3201, MPI3501 etc., the HDMI port will not output a signal. To switch back to HDMI display mode, execute: cd LCD-show/ sudo ./LCD-hdmi For touch screen calibration, install xinput_calibrator with: cd LCD-show/ sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb Follow the on-screen prompts after selecting 'Calibrate Touchscreen' from 'Preferences'. Reboot might be needed for calibration activation. Optionally, save touch parameters to 99-calibration.conf file. About Dual Use ABS Case Made from ABS material, supports the installation of a 3.5-inch touch screen (requires case cover removal). In typical use without a screen, the case allows for a cooling fan. Designed for Raspberry Pi 4 Model B, providing access to all interfaces like USB, Ethernet, A/V, micro HDMI, and more. Note: Model A1 allows GPIO and POE access, while A2 does not. Features two mounting holes for easy wall installation, especially useful when using a 3.5-inch touchscreen. Package Includes 1 x ABS Box Case 1 x Touch Screen 1 x Touch Screen Pen
