Discontinued

The µLCD-32PTU is a compact intelligent display module from 4D Systems, featuring a 3.2-inch TFT LCD (240 × 320) with integrated resistive touchscreen. Powered by the PICASO processor with the EVE (Extensible Virtual Engine) core, it serves as a ready-made GUI for embedded projects.

The module combines the LCD screen, audio amplifier with speaker, micro-SD card slot, LiPo battery support, and general-purpose I/O into a single unit. A simple 5-pin serial interface (VCC, TX, RX, GND, RESET) connects to any host device.

Warning: Using an FTDI breakout to program 4D screens can damage the driver. Use the 4D Systems µUSB-PA5 programming adapter instead.
