Review: Great display with better packaging and simplified wiring - This version of the Hosyund 4.0in 320x480 display fixes the 2 things I disliked about the original version (red PCB) - the additional header used for accessing the SD card, and using an SD card instead of a microSD card. This board is pin compatible with the old one on header J2 for the display and SPI (pins VCC through SDO(MISO)). I don't use touchscreen normally, so I can't confirm they are the same. Instead of having a separate SPI header for the SD card like the old version, this board adds the microSD chip select pin (SD_CS) to the main header, eliminating the 4 pin header for the SD card. This version uses a microSD card instead of an SD card. This saves a lot of space around the board when packaging it in a project. The microSD card is under the board, on the old version the SD card stuck out about 1/2" outside the edge of the board and took up a lot more space. Like the red board version, the display is clear, bright, and easy to read in bright environments. This display can be tricky to get set up. I use the Bodmer TFT_eSPI library. Search for that, there are videos and documentation available to help you get started. Great display, great price!
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.

### ⭐⭐⭐⭐ Nice display panel
*by S***Y on October 30, 2025*

Using this with an Arduino Mega 2560. First off, it just works. The display is top notch with black levels nearing OLED levels. The colors are bright and the images are sharp. The documentation is superb. The provided character font is not great. If I could figure out how to load a better font, it would get 5 stars. There is some text in the documentation suggesting it can be done, but I have not found any details on how that is accomplished. For static text, I just use a bitmap with a better font. My perspective is one of an EE with over 50 years of hardware and system software design experience.
