This is a plug-and-play 2.4" TFT LCD Shield designed specifically for the Arduino Uno. Unlike standard 2.4" displays (which use ILI9341 drivers), this module uses the HX8340-B driver with a 176x220 resolution. It features a resistive touch screen and an onboard MicroSD card slot.

Specifications:

• Driver IC: HX8340-B (8-bit Parallel Interface)
• Resolution: 176 x 220 Pixels
• Screen Size: 2.4 Inch Diagonal
• Touch Driver: Analog Resistive (Shared pins with display)
• Interface: Digital 8-bit Parallel (Pins 2-9) + Control (A0-A4)

Features:

• Direct Fit: Plugs directly onto Arduino Uno or Mega2560 without jumper wires.
• Touch Screen: Integrated 4-wire resistive touch panel.
• Storage: Onboard MicroSD card slot for loading images or logging data.
• Voltage: 5V compatible (Onboard 3.3V logic level shifting).

Pin Assignment (Arduino Uno):

• LCD Data: D2, D3, D4, D5, D6, D7, D8, D9
• LCD Control: A3 (CS), A2 (RS), A1 (WR), A0 (RD), A4 (RST)
• SD Card: D10 (CS), D11 (MOSI), D12 (MISO), D13 (SCK)
• Touch: D8, D9, A2, A3 (Shared)

Note: This display requires specific timing and initialization. Please use the TRONICLK_HX8340 library for correct operation, as standard libraries (like Adafruit_TFTLCD) will produce a white screen or garbage pixels.
