Description: The µLCD-32PTU is a compact Intelligent Display Module from 4D Systems packed with plenty of features, ready to become the GUI for your project, and capable of being an interface controller for a number of applications.

At the heart of the design is the PICASO processor, which is driven by a highly optimised virtual core engine called EVE (Extensible Virtual Engine). A whole bunch of hardware and software peripherals have been integrated into the design, to give you the freedom to adapt the module to suit almost any application.

The µLCD-32PTU is a combination of a 3.2” (240x320) LCD Screen, audio amplifier and speaker, micro-SD card connector, Lithium Polymer (LiPo) battery support, along with a group of general purpose input/output pins (GPIO's), including I2C and serial COMMS.

Note: The module can be switched to a "SGC" by changing the firmware. It's been brought to our attention that trying to program the 4D screens using an FTDI breakout can damage the driver. You'll need to use the FT232RQ USB to Serial which you can find in the related items below.

Dimensions: 56.32 x 92.19 x 15.9mm (including corner plates)

Features:

  • Low-cost 3.2" LCD-TFT display graphics user interface solution
  • 240 x 320 VGA resolution, RGB 65K true to life colours, TFT screen with Integrated 4-Wire Resistive Touch Panel
  • Easy 5 pin interface to any host device:
    • VCC, TX, RX, GND, RESET
  • Powered by the 4D-Labs PICASO processor
  • 14KB of flash memory for user code storage and 14KB of SRAM for user variables, or 14KB shared user code and program variables
  • 2 x Asynchronous hardware serial ports (COM0, COM1), TTL interface, with 300 to 600K baud
  • 1 x I2C interface (Master)
  • 8 x 16 bit timers with 1 millisecond resolution
  • 13 x General Purpose I/O pins. Supports fast 8-bit parallel data transfer through Upper 8 bits
  • On-board micro-SD memory card adapter for multimedia storage and data logging purposes. HC memory card support is also available for cards larger than 4GB
  • DOS compatible file access (FAT16 format) as well as low level access to card memory
  • Lithium Polymer battery support, with built in battery charger and automatic change-over
  • Dedicated PWM Audio pin driven by WAV files from micro-SD card
  • On-board audio amplifier with a tiny 8Ω speaker for sound generation and WAV file playback
  • Built in extensive 4DGL graphics and system library functions
  • Display full color images, animations, icons and video clips
  • Supports all available Windows fonts
  • A 30 pin header for I/O expansion and future plug-in daughter boards
  • 4.0V to 5.5V range operation (single supply)
  • Display Viewing Area: 48.60 x 64.80mm
  • 4 x corner plates with 2.7mm holes for mechanical mounting.

  • Does anyone know if this would work with the raspberry pi?

  • Programming cable is included? I see it in the picture but is not listed on the product. Thanks!

    • I believe the cable shown is listed, but it is just a flat ribbon cable, you will still need the USB to serial adapter to program the board.

  • The datasheet shows that this can be programmed with a proprietary USB cable, but I’m curious if it can be programmed with an FTDI breakout. Has anyone tried this?

    • i’ve run over a dozen of these via a USB to UART dongle picked up on ebay for $1. Warning, they used to claim that using any other cable would void your warrantee, not sure if that is still the case or not.

  • Please consider carrying the bezels for these in stock.

  • I need with CAPACITIVE touch panel with same size, are you sell that product? Thank You.

  • I was having trouble controlling the display and late last night discovered that the 5-pin ribbon cable had an open circuit on the green reset wire. I took the connector apart and the conductors are all cut right at the edge of the insulation where the crimping tool would have clamped down to close around the insulation. The mfg. should be notified to check the crimping setup. Jay. PS: I took a picture if you want to see it.

  • Silly question, how difficult would it be to work with this on an Arduino Pro?

  • Holy cow, that’s an amazing display! Anything it doesn’t do?

    • It won’t do SPI, and the compiler does not support double precision – the 16-bit integer arithmetic can be very limiting so don’t use it where you need wide ranges of numbers unless you want to write some double-precision routines yourself.

      • ^^This. I had to come up with some creative ways to use the onboard micro to handle some of the functions I needed - it was a fun challange though :)

  • Why is it listed as being 240x320? Shouldn’t that be 320x240? Or did everyone switch to using displays in portrait mode when I wasn’t looking?

    edit: I see, the viewing angles are made for portrait mode, so obviously that makes it 240x320.

    • The programming environment is also amazingly easy. You can download it for free from their web site. I was just playing with the visi-genie mode. And you can program it in landscape or portrait setting.
