This is a 3.0 inch TFT LCD expansion board using standard Arduino Shield interface and it has good compatibility. It integrates a 3.0-inch LCD, I2C temperature sensor, TF card holder, level conversion circuit, and the secondary development is less difficult.
With GPRS module, you can design your Arduino phone.
With NFC reader module, you can create access control systems with the photos show.
Can use it directly to display characters, graphics and BMP format images.
Compatibility: As the SD card is connected to SPI pins of ICSP interface, compatible with Arduino UNO R3 / Arduino Mega2560 / Arduino Leonardo
Arduino library: TFTLibrary and Adafruit_GFX;
Display size: 3.0 inch;
Operating voltage: 5V;
Logic level: 5V / 3.3V;
On-board 3.3V / 300mA regulator circuit;
Operating current: the maximum is 150mA
Use the A0 ~ A3 pins, D4 ~ D13 pins. And I2C interface, D0 / D1 / D2 / D3 is available, please refer to the product schematics for the details.
You can modify the pad settings (Desolder VCC jumper and solder D3jumper), use D3 pin to control the brightness of backlight
Onboard Micro SD slot, support Micro SD / TF Card;
Onboard LM75 temperature sensor: default I2C address is 0X48, scale is -55 ~ 125'C
Great for DIY
