4D 無CD-220RD Round Display Module

  • Powerful DIABLO16 Processor
  • 32Kb of User RAM
  • 6 banks of 32750 bytes of Flash memory
  • Round TFT LCD
  • Unique Display Solution

The uLCD-220RD is a unique 1.38" Round LCD Intelligent Display Module powered by the 4D Systems DIABLO16 Graphics Processor.

The uLCD-220RD is designed for applications such as gauges and instruments or for special applications such as robotics.

Driving the display and peripherals is the DIABLO16 processor, a very capable and powerful chip which enables stand-alone functionality, programmed using the 4D Systems Workshop 4 IDE Software. The Workshop IDE enables graphic solutions to be constructed rapidly and with ease due to its design being solely for 4Ds graphics processors.

The display module has an array of features including PWM, micro-SD memory storage, general purpose I/O including Analog Inputs, multiple TTL Serial, I2C and SPI channels, Quadrature Input, Pulse Output and multiple millisecond resolution timers, amongst many more features.

The uLCD-220RD features a 30 way 2.54mm pitch male pin header, where all of the IO available on the Diablo16 processor have been broken out for the User. It also features a 10 way 2.54mm pitch male pin header which is common to a majority of 4D Systems display modules, and is used for programming the module with our Workshop4 IDE, using a Programming Cable or Adaptor.

If you are after a unique display solution for your project, maybe an Automotive Gauge or Instrument Dial, or even a Robot Head, look no further than the 4D Systems uLCD-220RD Round TFT LCD Intelligent Display Module.
