SIM521 7″ HMI
The SIM521 features a premium, high resolution 7″ 800×480 color LCD powered by the STM32H750XB MCU with 480MHz Arm Cortex-M7 MCU and 1MB integrated RAM. Utilizing our proprietary SHIPEngine firmware, the SIM521 delivers a large array of options for front panel applications with industrial, commercial, and medical applications in a small package.
Featuring built-in RS485/UART and high-speed USB connectivity, SIMx21 family members are easily integrated into existing system designs. The 30-pin expansion connector provides further expandability to custom daughter-cards or off-the-shelf Serious Communications/Control Modules for extensive connectivity (including WiFi, Bluetooth, Ethernet, RSxxx, CAN, and more) as well as powerful system control.
