Description
2.0 inch TFT LCD Touch Screen Adapter Board Resistive Touch Panel 3.3V with Pen Resistive Touch Screen Monitor ST7775R
Product Description
This is a 2.0-inch TFT LCD expansion board. The monitor has a built-in controller with RAM buffer, so almost no work is done by the microcontroller. The module converts the pins of the LCD screen into 2.54mm pitch pin headers, reducing the difficulty of secondary development. With GPRS module, you can make DIY mobile phones. With NFC read-write module, you can make access control and photo display system. With voltage and current sensors, oscilloscopes can be made.

-UNO R3 and its compatible motherboard can directly use it to display characters and graphics, BMP format pictures, and touch control -Compatibility: Since the logic level is 3.3V, it is directly compatible with 3.3V motherboards. When connecting with 5V motherboards UNO R3 / Mega2560 / Leonardo, you need to add a level conversion circuit.
-The LED pin can be used to connect an external backlight control circuit to control the brightness of the backlight, or it can be directly connected to GND to keep the backlight LED on -Very suitable for making digital photo frames, oscilloscopes, function generators, detection system displays
