SIM231 4.3″ HMI

SIM231 is a mature product — see the SIM252 for new designs.

SIM231 is an Extended Lifetime Product.

With a cost-effective 4.3″ 480×272 LCD and powered by a 96MHz Renesas RX631 MCU with Serious Gatling™ Technology for rapid-fire 24-bit color delivery and ambient light sensing, the SIM231 can deliver an outstanding front control panel experience for your product.

Standard high speed UART, SPI, and power connectivity is provided by a 16-pin Power/Communications connector — perfect for simple wire-harness attachment to existing systems. A low profile, high-density module-to-module 60-pin expansion connector supports easy daughter card development for proprietary system integration. Or, choose one of the Serious Communications Modules to provide the communications flexibility you need, including industrial, IT, and IoT connectivity.

Explore these options compared to the SIM231:

  • SIM152 for similar capabilities in a cost effective, very compact 3.5″ form factor
  • SIM252 for more performance in a more cost effective, modern product line
  • SIM352 for a larger, high resolution 5″ experience
  • SIM562 for higher performance, including video playback
  • SIM862 for higher performance, including video playback, with a big, bold 10.1″ LCD
