arduino lcd module sd card reader made in china

I added a spare 2 pin header I had laying around although only 1 pin is used (SD_CS). The other 3 I just bypassed the useless 1K resistors (I will only ever use this with a DUE so they are redundant (and could cause speed problems)) and connected them to the TFT equivalents (MISO/MOSI/SCK).

What I understood was - ignoring the SD card module, they are using an LED driver IC to control the backlight, and a voltage regulator(with some auto reset IC) to feed the correct voltage to the LCD. Apart from that there"s some bypass caps on VCC and, some diodes on the LED driver IC.

SD Card Reader Writer Module for Arduino with the onboard 3.3V regulator. It is easily interfaced as a peripheral to your Arduino, and other embedded boards and microcontrollers. Through programming, you can read and write to the SD card over SPI interface.

Storing data is one of the most important parts of every project. There are several ways to store data according to the data type and size. SD and micro SD cards are one of the most practical ones among the storage devices, which are used in devices such as mobile phones, minicomputers and etc.

The SD and micro SD card modules allow you to communicate with the memory card and write or read the information on them. The module interfaces in the SPI protocol.

These modules can not handle high-capacity memory cards. Usually, the maximum identifiable capacity of these modules is 2GB for SD cards, and 16GB for micro SD cards.

Opens a file on the SD card in reading or writing mode. (If you leave the mode section blank, the file will open in reading mode by default) If the file is opened for writing, it will be created a file with this name if it doesn’t already exist.

Create an entry/exit control device. Using the RFID module and Arduino, save entrance and exit time for several persons on the memory card. (Consider an RFID card for each person)

This ST7735S 1.8" TFT Display features a resolution of 128×160 and SPI (4-wire) communication. Integrated with an SD card slot, it allows to easily read full-color bitmaps from the SD card. The module provides users with two wiring methods: pin header wiring and GDI (General Display interface). You can directly use an FPC cable to connect the display to any controller with GDI interface like FireBeetle-M0. Plug and play, easy to wire. Besides, the display supports low refresh rate and offers good display effect and strong versatility. It can be used in applications like sensor monitoring and alarm, Arduino temperature monitor, fan controller, etc.

This product is a breakout module that features SPI communication mode and onboard GDI interface, which could reduce the complexity of wiring. It can easily display the read content from the SD card.

The Graphic LCD screen is a backlit TFT LCD screen with headers. You can draw text, images, and shapes to the screen with the GLCD library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.

The screen"s headers are designed to fit into the socket on the front of Esplora, but it is compatible with any AVR-based (Uno, Leonardo), Datasheet You can use this module with Esplora.
