Teyleten Robot 1.28 Inch TFT LCD Display Module Round RGB 240 * 240 GC9A01 Driver 4 Wire SPI Interface 240x240 PCB for Arduino 3PCS

The media could not be loaded. These round 240x240 TFT displays look great. All three displays work with no problems. They use RGB565 16-bit color format = 65K colors. They work with the Adafruit and TFT_eSPI Arduino libraries. The clock video uses the LVGL Arduino library.

Each device came in a separate plastic case within an anti-static bag.Below is the minimum config (User_Setup.h) you can use for this display and it will work. Change PIN numbers to suit your needs for your ESP module.#define GC9A01_DRIVER// For CYD ESP32-2432S028#define TFT_WIDTH 240#define TFT_HEIGHT 240// For ESP32 Dev board (only tested with GC9A01 display)// The hardware SPI can be mapped to any pins#define TFT_MOSI 21 //SDA In some display driver board, it might be written as "SDA" and so on.#define TFT_SCLK 22 //SCL#define TFT_CS 16 //CS Chip select control pin#define TFT_DC 17 //DC Data Command control pin#define TFT_RST 4 //RST Reset pin (could connect to Arduino RESET pin)// Comment out the #defines below with // to stop that font being loaded// The ESP8366 and ESP32 have plenty of memory so commenting out fonts is not// normally necessary.

These are good, the clarity on the screens is sharp and the colors stand out against a very black background. My main complaint is that they are not bright enough, and there is no pin to control the brightness of the backlight.That said, I had no issue connecting these to either ESP32 or Pico 2W. ESP32-S3-DevKitC1 however did not work and I suspect it was the library and not the display. No hit on my rating from that.They came with sticky-covering on the display surface to protect it, a plus for me. They ran on 3.3 just fine. Adequately marked for pin designations. I WILL buy more of these to fill out my gauges for all sorts of things, unless I find a better deal with a brighter display that has a pin to PWM the back light.

I have used several of these displays already. They are easy to use, bright and sharp.

I used these for the "Eyes" of a costume headpiece and they are perfect. Combine them with glass cabochons and a flexible led strip and you get what you see in the pic. I have an esp32 displaying an animated gif on repeat hooked to two of these.These are easy to work with, inexpensive and they are just the right size for eye projects ;)~J

Nice displays, work well

I’ve been testing a few different screens for various projects, and these screens have been my favorite of the many I’ve tried. The resolution is so sharp. Ive layered text over photos and video and it’s super clean, very impressive for its size. The shape of the screen is also fun and different.My only complaint is the placement of the pins is a bit limiting. I would like to be able to mount it so it lays flush on whatever device I design for it, but the way the connector attaches makes that impossible.Still a great screen and would definitely recommend.

The media could not be loaded. Round displays like this one are a throw-back to the days of round analog displays. Easy to interface with using SPI. It is backlit, but that is not obvious from the description. I have one guarding my bottles of Scotch with an "Alien Eye" GIF running on it as see in the video.
