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” (240×320) 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. Check the Recommended Items section below for 4D Systems’ µUSB-PA5.
