Given that the current TFT (Thin Film Transistor) in your project is the NX3224T028, this means it's a 2.8" Nextion HMI LCD Touch Display. Here's a similar one for a replacement:
Designator: TFT2
  • MPN: ILI9341 2.8'' TFT Touch Display
    • This is a 2.8" SPI TFT LCD Display module that also comes with a Touch Panel, similar to the one you are replacing. It's manufactured by Adafruit. It's a reliable and widely-used module suitable for many applications. The ILI9341 TFT display is a general-purpose TFT module that operates over a 4-wire SPI interface which allows it to be easily interfaced with a microcontroller like the Blue Pill on your project.
  • Pins:
    • 1 (name: GND),
    • 2 (name: VCC),
    • 3 (name: CS),
    • 4 (name: RESET),
    • 5 (name: A0/D/C),
    • 6 (name: SDI(MOSI)),
    • 7 (name: CLK),
    • 8 (name: LED),
    • 9 (name: SDO(MISO)),
    • 10 (name: T_CLK),
    • 11 (name: T_CS),
    • 12 (name: T_DIN),
    • 13 (name: T_DO),
    • 14 (name: T_IRQ)
Note however that the interfacing method with the ILI9341 2.8, TFT Touch Display is slightly different compared to the Nextion, as the ILI9341 uses SPI communication. The Blue Pill microcontroller should handle this without a problem, you just need to adapt your code accordingly.
Remember to refer to the manufacturer's datasheets and resources for exact pin connections and operational details.

Given your requirements, a suitable replacement could be the Adafruit RA8875 Driver Board for 40-Pin TFT Touch Displays.
Here's the new component with a brief description:
Designator: TFT2
  • MPN: Adafruit RA8875
    • The RA8875 is a powerful TFT driver chip. It is a perfect choice for controlling a 40-pin TFT with parallel interface. It's designed by Adafruit and comes with a built-in graphics primitive. This makes creating complex graphical displays easier. It can control TFT displays up to 800x480 in size.
  • Pins (27 in total):
    • 1-8 (name: DB0-DB7 for the parallel data bus)
    • 9 (name: RD)
    • 10 (name: WR)
    • 11 (name: CS)
    • 12 (name: RST)
    • 13 (name: IRQ)
    • 14 (name: WAIT)
    • 15 (name: INT)
    • 16 (name: PS2-Y)
    • 17 (name: PS2-X)
    • 18 (name: VIN)
    • 19 (name: 3V3)
    • 20 (name: GND)
    • 21 (name: SDA)
    • 22 (name: SCL)
    • 23-27 (name: LED, available for different LED connections)
Element Properties:
  • Manufacturer Name: Adafruit
  • Designator Prefix: TFT
Please make sure to also acquire a TFT display compatible with this driver board. The Adafruit server has many options, including the popular 800x480 5" and 480x272 4.3" displays.
As always, ensure to consult the manufacturer's datasheet and resources for the exact operational details and connectivity guidelines.

If you're looking for a TFT driver that supports 320x240 displays with parallel interface and pin count not exceeding 28, a suitable option would be the ILI9341 2.2" TFT (SPI flash filesystem version). It's worth noting that this particular display supports a serial SPI connection, but there are other models available or similar chipsets that can support parallel data connections.
Designator: TFT2
  • MPN: ILI9341
    • The ILI9341 is a QVGA (Quarter VGA) driver integrated circuit that controls a variety of LCD displays. It provides an 18-bit parallel interface.
Here are the pins output:
  • LEDK (Backlight cathode)
  • LEDA (Backlit anode)
  • VSYNC
  • HSYNC
  • PCLK
  • DBI18 (D8...D15)
  • DBI09 (D0...D7)
  • CSX
  • D/CX
  • WRX
  • RDX
  • TE
  • IM0
  • RESET
  • GND
  • VDD
  • VCI
  • IOVCC
  • SDI (Serial Data Input)
  • SDO (Serial Data Output)
  • RD (Read)
  • WR (Write)
  • RS (Register Select)
  • CS (Chip Select)
  • RESET
Element Properties:
  • Package or Case Code: Module
  • Manufacturer Name: ILI9341
  • Designator Prefix: TFT
Note that the parallel interface pins (DBI09 and DBI18) handle the parallel data transfer, WR is a write strobe, CSX activates the interface, D/CX distinguishes between data and commands, RDX read operation, and WRX write operations.
Please consult the manufacturer's data sheet for complete technical details.

Given your requirement, a suitable TFT shield for an Arduino would be the 2.8" TFT Touch Shield for Arduino with Resistive Touch Screen by Adafruit.
Designator: Shield1
  • MPN: Adafruit 2.8" TFT Touch Shield
    • This shield can easily plug into an Arduino board, providing a 2.8" TFT display with 240x320 resolution. It also comes with a resistive touch screen, as well as a microSD card slot for additional storage needs. It uses SPI for communication, meaning it is only using a few of the Arduino's pins.
Here are the main features:
  • Screen Dimensions: 50mm x 69mm
  • Overall shield Dimensions: 69mm x 54mm x 22mm
  • Resolution: 240x320
Element Properties:
  • Manufacturer Name: Adafruit
  • Designator Prefix: Shield
The output pins depend on the Arduino type you're connecting it to, but you'll primarily use the SPI (Serial Peripheral Interface) pins, plus a few additional control lines (responseData, reset, etc.).
Please keep in mind that this is a 2.8" screen. If you wanted a different size, the manufacturer offers a variety of other sizes as well. As always, don't forget to check the manufacturer's data sheet for complete technical details.
