DFI M8MP553-ECC-41QDI NXP i.MX 8M Plus Quad 3.5″ SBC with 9 to 36 V DC Input, 4GB LPDDR4 Memory and Wide Temperature

An operator panel on a packaging line, or a gateway translating fieldbus traffic to a plant network, spends its cycles on the user interface and protocol stacks rather than on AI. The M8MP553-ECC-41QDI fits that work as the quad-core, 4 GB build of the DFI M8MP553 series, a 3.5″ SBC rated from -30 to 80 °C.

Its industrial-grade quad-core NXP i.MX 8M Plus runs four Arm cores at 1.6 GHz, with 4 GB of soldered LPDDR4, 16 GB of eMMC 5.1 and a microSD slot. This quad-core part has no NPU, so the board suits HMI and control software rather than neural networks. The Vivante GC7000UL GPU renders the interface, and the video engine decodes H.265 and H.264 at 1080p60 for camera views or instruction videos on the panel. Linux Yocto 5.0 is the default image, with Debian 12 and Android 10 on request.

Dual-channel LVDS at up to 1920 x 1200 drives a built-in panel while HDMI at 1920 x 1080 runs a second screen. Two GbE ports on AR8035 PHYs separate the machine and plant networks, two CAN 2.0B ports reach drives and controllers, and serial covers RS-232, RS-232/422/485 and a two-wire RS-485 terminal block, with 8-bit DIO. Two USB 3.1 Gen 1 and two USB 2.0 Type-A ports sit on the edge, M.2 sockets take 4G (with a nano SIM slot), Wi-Fi and Bluetooth, and a Micro USB download port serves as a service port for flashing.

The M8MP553-ECC-41QDI is fanless, runs from 9 to 36 V DC on a terminal block (the full temperature range applies from 9 to 24 V, with 36 V supported up to 70 °C) and carries CE, FCC, UKCA and RoHS compliance. DFI quotes a typical 3.6 W and a 5.28 W maximum for the quad-core part at 12 V. The M8MP553-ECC-81QDI doubles the memory to 8 GB, and the M8MP553-ECC-21DLI trades two cores for the 2.3 TOPS NPU.
