Arduino LCD Module and SD Card Reader (Retired)

$30.00

We’re really excited to now offer the Arduino LCD Module with SD Card Reader! The board consists of a backlit TFT LCD screen with embedded holder for micro-SD card. This Arduino accessory board also has headers so it can be easily attached to your application. The screen's headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc.).

You can draw, text, create images and shapes directly to the screen with the Graphic LCD (GLCD) library. The micro-SD card can be used, among other things, to store bitmap images for the display screen. Making it possible to do a whole slew of visualizations more easily!

How to use Arduino LCD Module and SD Card Reader

The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino screen. The Arduino specific additions were designed to work as similarly to the Processing API as possible.

The library is backwards compatible, which means you can still use the Adafruit functions.

The TFT library relies on the SPI library, which must be included in any sketch that uses the screen. If you wish to use the SD card, you need to include the SD library as well.

Connecting to other Arduino boards
Even if the screen’s headers are designed to fit into the socket on the front of the Arduino Esplora or the Arduino Robot but, this module is compatible with any AVR-based Arduino (Uno, Leonardo, etc…) or with the Arduino Due. If you want to use one these other boards, some slight changes on connections are required.

You can either connect the screen with hardware SPI pins, or define your own set of pins. Using the hardware SPI is faster when drawing to the screen.

Arduino Uno:
Connect power and ground to the breadboard.

GLCD_logo1

Connect the screen to the breadboard. The headers on the side of the screen with the small blue tab and arrow should be the ones that attach to the board.

GLCD_logo2
Pay attention to the orientation of the screen, in these images, it is upside down.

Connect the pins following this default configuration:
+5V:
+5V
MISO:
pin 12
SCK:
pin 13
MOSI:
pin 11
LCD CS:
pin 10
SD CS:
pin 4
D/C:
pin 9
RESET:
pin 8
BL:
+5V
GND:
GND

Uno_TFTsm

Connecting the pins in the proper way, you can see the lcd screen working with your Uno (or Duemilanove) just uploading the simple “TFTBitmapLogo” sketch.

Arduino Leonardo & Arduino Yun:
The Arduino Leonardo & Arduino Yun use different pins to be compatible with the lcd screen. To set the pins MISO, MOSI and SCK, you have to use the ICSP terminals.
+5V:
+5V
MISO:

Miso pin (white wire on ICSP)
SCK:
Sck pin (brown wire on ICSP)
MOSI:
Mosi pin (yellow wire on ICSP)
LCD CS:
pin 7
SD CS:
pin 8
D/C:
pin 0
RESET:
pin 1
BL:
+5V
GND:
GND
The image below shows an Arduino Leonardo but it works for an Arduino Yun too.

The screen will show this message: “Arduino TFT Bitmap Example. Open serial monitor to run the sketch”. Open the serial monitor to view the Arduino Logo.
Arduino Mega 2560 e Mega ADK:
To connect the lcd screen to a Mega board, use this pin configuration:
+5V:
+5V
MISO:
50 on Mega 2560 (Miso on ADK)
SCK:
52 on Mega 2560 (Sck on ADK)
MOSI:
51 on Mega 2560 (Mosi on ADK)
LCD CS:
pin 10
SD CS:
pin 4
D/C:
pin 9
RESET:
pin 8
BL:
+5V
GND:

Arduino Due:
To connect the lcd screen to an Arduino Due, use this pin configuration and don’t forget to set the right value for the variable “sd_cs” (#define sd_cs 7) in the sketch:
+5V:
+3.3V
MISO:
Miso pin (white wire on SPI)
SCK:
Sck pin (brown wire on SPI)
MOSI:
Mosi pin (yellow wire on SPI)
LCD CS:
