Feature: 1. MAIN USE: Providing control and visual interfaces between people and processes, machines, applications, or devices is the best solution to replace traditional LCD and LED's. Mainly used in the Internet of Things (IoT) or consumer electronics products. 2. EASY USE: The TFT board uses only one serial port for communication. Eliminates the hassle of user wiring. And it's easy to adapt to existing projects. The user only needs to provide a UART for use. 3. POWER DETAILS: You can supply HMI 3.5 from the 5V pin on the microcontroller, but this is not recommended. Insufficient power can damage the screen. Please use the power board provided with the connection. 4. FUNCTIONS INCLUDES: A 3.5 inch 480 x 320 TFT resistive touch screen display, 16MB flash memory, 2KB RAM, and 65000 colors. Visible area, 73.44mm (length) x 48.96mm (width); Uploading TFT files through an storage card is faster than 4 pin serial ports, but the credit card is in FAT32 format and does not exceed 32GB. 5. APP DRIVE: With driver software, the screen is more convenient to operate. Ideal replacement for the old and damaged parts.
