3.5 TFT 320x480 + Touchscreen Breakout Board w/MicroSD Socket [HXD8357D]

A large 3.5" colour TFT LCD breakout board with a built-in resistive touchscreen and a microSD card socket. The 480×320 pixel display is driven by the HX8357D chipset and features a bright 6-LED white backlight. The breakout board includes 3–5 V level shifters, making it compatible with both 3.3 V and 5 V microcontrollers.

The display supports two interface modes: 8-bit parallel (12 lines total) for maximum speed, or SPI (5 lines) for a simpler wiring setup. The resistive touchscreen requires 2 digital and 2 analogue pins for direct reading, or can be driven via an external touch controller over I2C/SPI (sold separately). In SPI mode, the onboard microSD socket can be used to load and display bitmap images.

Key Features

• 3.5" TFT Display – 480×320 pixels with individual RGB pixel control
• HX8357D Driver – Built-in controller with RAM buffering for minimal MCU overhead
• Dual Interface – 8-bit parallel (fast) or SPI (fewer pins)
• Resistive Touchscreen – Detects X, Y, and pressure (Z)
• MicroSD Card Socket – Load images from a microSD card in SPI mode
• 3–5 V Level Shifting – High-speed level shifters for broad microcontroller compatibility
• Bright Backlight – 6 white LEDs for clear visibility
