Review: Recommended Drivers Work - This is for the 4" 320x480 capacitive touch display with ST7796s. I first tested out the display itself, and found the TFT_eSPI to work well. For reading the touchscreen, I only really tested position and haven't looked into gestures yet, but I found that both RAK14014-FT6336U and the Arduino-FT6336U libraries worked equally well for what I tested. The RAK library actually used up a bit more program memory, about 240 bytes more, so if your processor is small in that department, might consider that. Here are some tidbits that I needed to learn through experimentation that might help others get running quicker: 1) SPI interface to the display runs well at 80MHz. I used ESP32 DEV, so no problem. 2) On ESP32, use default SPI pins in order to use hardware driver, which is fastest. 3) On I2C interface for touchpad, use default pins for SDA and SCLK. Easiest way to check which pins these are is to print out SDA and SCLK to the serial port. 4) The FT6336U interrupt pin is mostly useful to wake up the processor while in a sleep state. During normal operation, interrupts constantly come in and cannot easily be used to determine when a touch has happened. Need to poll the TD_STATUS register to see if non-zero and not use the interrupt line in normal operation. 5) TFT_eSPI is a very inclusive library, but you will need to alter it unless you have a board and pin setup combo that matches one of the many examples. This is not documented well. I recommend taking the SetupX_Template.h file in the User_Setups folder, configure it according to the comments in the file, save it as a new filename, and then you only need to change a single line in the standard library files from that point onwards, even if this library gets updated in the future. Then you can either copy this custom name file to the User_Setup.h file and overwrite the original. Or, everytime a new library version comes out, just edit the User_Setup_Select.h file to comment out the User_Setup.h and add a line to use the new file you created. Both ways work well. But expect that you will need to do this bit of customization to the library. 6) I2C address for the touchpad is as in the FT6336U library, address 0x38. You can also find example scanner sketches online which will confirm your board's touchpad I2C address. Overall, the display is a great value - nice and bright, large, and with a capacitive touchscreen that pretty much works out of the box without calibration.
Review: Nice display - Nice display well made. Sharp characters. I did have some problems with the tutorial but figured it out in a few hours.

### ⭐⭐⭐⭐⭐ Nice display
*by D***H on July 30, 2026*

Nice display well made. Sharp characters. I did have some problems with the tutorial but figured it out in a few hours.

### ⭐ Misleading Product - Not a True SPI ST7796S Display
*by A***R on August 3, 2026*

This display is advertised as an SPI‑driven ST7796S module, but the unit I received does not behave like a real SPI device. The pins are labeled for SPI, yet the controller never responds to SPI commands from an ESP32‑S3 or ESP32. There is no documentation, no schematic, and no configuration pads to confirm the interface mode. After extensive testing, it appears the SPI pins are not actually connected to the controller, making the display unusable for any SPI project. If you need a reliable SPI TFT for ESP32 development, look elsewhere.
