DFI M8MP553-ECC-21DLI Dual-Core NXP i.MX 8M Plus Arm Single Board Computer with 9 to 36 V DC Input, 2GB LPDDR4 Memory and -30 to 80 °C

A vision check on a conveyor, or a sensor gateway that flags abnormal readings, often needs a small neural network more than raw CPU power. The M8MP553-ECC-21DLI covers that case as the dual-core build of the DFI M8MP553 series, an Arm single board computer and the build in the series that carries the NPU of the NXP i.MX 8M Plus.

Its industrial-grade dual-core i.MX 8M Plus runs at 1.6 GHz with an NPU rated at 2.3 TOPS, which suits compact classification and detection models running beside the control code. Memory is 2 GB of soldered LPDDR4, with 16 GB of eMMC 5.1 and a microSD slot for storage. The Vivante GC7000UL GPU and video engine decode H.265, H.264, VP9 and VP8 at 1080p60 and drive HDMI plus dual-channel LVDS at the same time. Linux Yocto 5.0 is the default image, with Debian 12 and Android 10 on request.

Two GbE ports on AR8035 PHYs and two CAN 2.0B ports connect the board to a machine network, drives and PLCs. Serial covers an RS-232 header, an RS-232/422/485 header and a two-wire RS-485 terminal block on the rear, with 8-bit DIO for discrete signals. Two USB 3.1 Gen 1 and two USB 2.0 Type-A ports face outward, with two USB 2.0 headers inside. M.2 B-key and E-key sockets take 4G with the nano SIM slot, Wi-Fi and Bluetooth, and a Micro USB download port serves as a service port for flashing.

The M8MP553-ECC-21DLI runs from 9 to 36 V DC on a terminal block, with the full -30 to 80 °C range rated at 9 to 24 V and 36 V supported up to 70 °C. It is fanless, has a programmable watchdog and carries CE, FCC, UKCA and RoHS compliance. Where the application needs more CPU than AI, the M8MP553-ECC-41QDI has four cores with 4 GB, and the M8MP553-ECC-81QDI adds 8 GB for larger HMIs or protocol stacks.
