Product Overview
The EDA ED-HMI3120-116C is an 11.6-inch industrial Human-Machine Interface (HMI) powered by the Raspberry Pi CM5. It features a high-resolution, 1920x1080, multi-point capacitive touchscreen. The device is equipped with a Broadcom BCM2712 quad-core Cortex-A76 (ARM v8) 64-bit SoC running at 2.4GHz. It supports up to 16GB of LPDDR4 RAM and 64GB of eMMC storage, with expansion options via Micro SD card and M.2 NVMe SSD. Connectivity includes dual LAN ports (1 x Gigabit Ethernet, 1 x 100M Ethernet), four isolated RS232/485 ports with electrostatic and surge protection, and integrated 2.4GHz & 5GHz dual-band Wi-Fi, Bluetooth, and optional 4G LTE. The HMI offers a wide voltage power input range (DC 12V~24V) with built-in reverse polarity, overvoltage, and overcurrent protection. Additional features include an integrated supercapacitor (optional) for backup power, RTC, Watch Dog, EEPROM, and crypto authentication. The unit is designed for embedded installation and is compatible with VESA standard bracket mounting.
