Driver IC: ST7735R
Resolution: 128 x 160 pixels
Features:
- Can help you to get rid of the Arduino serial monitor.
- Tested with Latest Arduino 1.6.5.
IO interface:
1. RESET --directly to the microcontroller IO
2. CS --directly to the microcontroller IO
3. A0 --IO control registers select
4. SDA --IO control data transmission
5. SCL --IO control SPI bus
6. BL--High Level 3.3V backlight on
Package Include:
1 * 1.8" ST7735R SPI TFT LCD Display Module
Note:
Please contact us for documents and driver if you need. Please noted this LCD is 3.3V, which can not receive 5V signals from the Arduino, so please use a 1k series resistors between GPIO lines on a 5V arduino and this LCD, power this LCD with 5V but drive it with 'level shifted resistor' GPIO lines.
Besides, you could use mcifriend 2.8 inch TFT LCD library to get it to work, it will work fine with the Mega or Uno.

My daughter ordered it for school project but she didn't use or test it until out of our return period. When she tested it, it was not working. I highly doubt about the quality of the item.

Not bad for the price.The board pinouts are misleading or mislabeled.I wasted a LOT of time trying to find a working example of the software.Using an ESP32, I finally found an Arduino IDE 2.x example that worked the first time."Adafruit ST7735 and ST7789 Library > graphicstest"The display uses an ST7735 controller.I redefined the software TFT_xxx pins and Winner Winner Chicken Dinner!I didn't try the SD card interface.

I bought this LCD Display for a university course that I'm taking. The screen itself works amazingly with the breadboard that I had on hand and the tm4c123 microcontroller that we all used in the class. On both sides of the screen are indicators of what each pin should be assigned/connected to on the microcontroller. A big plus with this screen in comparison to others on the market is that it comes with connector pins connected to it already. Many people in my class had to learn how to solder and sloppily connected external pins to their other screens. That's most certainly not a problem here! Additionally, this screen had an SD card, if i remember correctly, that allows for more functionality. The screen has a full range of colors and allows both text and manually imported sprites to be displayed onto it. I'm not too sure if that all deals with the drivers I mention later or the screen itself, but its most certainly a plus in its own aspect. The LCD is built well and at no moment in time was I scared about it breaking - I even remember throwing it in my backpack connected to a bunch of wires while rushing to class on multiple occasions.The only complaint that I have with this screen is the lack of "drivers" that it has to display more complicated graphics. One specific example that I remember dealing with was that there is no horizontal orientation change feature. To display graphics horizontally, I had to rotate them in photoshop manually and import them into my program like that. This made things like positioning the sprites and graphics and, more importantly, edge detection more complicated as I had to account for the changed position basis (originally being the bottom left corner but being changed to the top left for the sprites when the screen itself is rotated).Overall, this is a great buy for someone looking for a cheap screen with great build quality, ease of use, and versatility in use with a multitude of microcontrollers.

This is a REALLY terrible display, in so many ways! For starters, the whole ST7735 line has around half a dozen versions, and this one isn't exactly match any of them! It doesn't even match other ST7735R screens I've found! From what I can tell, it's a whole new thing that uses most of the setup of the original board, but counts colors as Blue-Green-Red, instead of the INDUSTRY STANDARD Red-Green-Blue.Of course, you might not be able to tell the colors are off because the display is so dull and washed out. Even if you manage to get it working, which is unlikely, all of the colors are shades of pastel. I haven't seen a color LCD this bad in over 10 years.So it's hard to use, hard to see. On top of it all, it's not really that much cheaper then other displays you can buy on Amazon. You can get some deals direct from China, but otherwise, you're only saving a dollar or two on these lemons. Do yourself a favor, skip the whole ST7735 line, buy something else. Those GC9A01 displays are really great! Or maybe a nice OLED? Just avoid this trash!

Used with an Arduino Uno. No stuck pixels. Used 3.3 volts exclusively. CLK to SCL w/1K resistor; DIN to SDA w/1K resistor; D/C to A0 w/1K resistor; CS to CS w/1K resistor; and Reset to RST w/1K resistor. BL and Vcc connected directly to 3.3 volts. GND, of course, to Gnd. All this resulted in a beautiful display.

Easy to get working on a 3.3V device. I'm using an ESP32. The pin out is not intuitive. There is a MOSI pin but that is for the SD card. The SDA pin is the SPI MOSI. There is an SCK pin but that is also for the SD card. The SCL pin is for the SPI clock. A0 is the DC (data/command) pin. My display had negative colors but that was easy to fix in code using the INVON (0x21) command. Also the display is BGR instead of RGB, but most drivers support both.Unfortunately, these look like factory rejects because they have stuck pixels which spoil the display (see photo of dogs).Update: The seller reached out to me after seeing my review and sent me a replacement for free. Unfortunately the replacement is worse than the original (see the 2nd photo with the fonts), but I do appreciate the excellent customer service.

great screens! Took a little while to get here but now they're here they work fabulously.A tip for those starting out with arduino: you'll want to put 1.2k resisors between the screen and your logic pins because they will not tolerate 5 volt signals from the arduino.

cheap and easy lcd display for arduino. five dollars. can't complain. use adafruit drivers. NOTE, THIS IS 3.3V. for a cheap way to interface, use 1k series resistors between GPIO lines on a 5v arduino and this device. power this device with 5v but drive it with 'level shifted resistor' cpio lines. yes, they are slower than normal 74h4050 cmos chips but they also are likely things you already have in your parts box, amiright?
