Tiny module combines i.MX8M Mini and rich I/O

Feb 18, 2021 — by Jeff Child 988 views

ICOP’s NX8MM-D168 is a 35 x 55mm Linux-friendly module featuring the i.MX8M Mini, 2GB LPDDR4 as well as eMMC, GbE, 2xUSB, MIPI-DSI and -CSI, PCIe, UART, SPI, I2C and PWM. The module provides a 168-pin board-to-board connector.

ICOP Technology has released its NX8MM-D168 module based on NXP’s i.MX8M Mini SoC. The NX8MM-D168 runs Yocto Linux and Android 9 on the 1.6GHz i.MX8M Mini.  NXP’s Cortex-A53-based i.MX8M Mini uses a more advanced 14LPC FinFET process than the i.MX8M but doesn’t share its support for HDMI 2.0 and USB 3.0. The NX8MM-D168 board uses a 168-pin board-to-board connector for configurable I/O expansion and has soldered-on LPDDR4 and eMMC.

The NX8MM-D168 appears to be a significant departure for the Taiwan-based ICOP, which has previously focused on embedded boards and systems based on the x86 Vortex series CPUs from its sister company DM&P Group, along with some Intel processor-based based boards. A recent ICOP SBC we covered is the “VEX2-6415”. The NX8MM-D168 appears to be the company first foray into i.MX8M Mini-based boards.

There’s been a slew of products we’ve covered over the past 12 months based on the i.MX8M Mini. The most recent of these include Gateworks’ “Venice” family of SBCs, Avnet’s “MaaxBoard Mini” SBC, and Keith & Koep’s “Myon II” module.

The tiny the NX8MM-D168 measures 35 x 55mm, a little less half the size of a credit card. While not the smallest module we’ve seen by far, it’s worth comparing to Keith & Koep’s “Myon II” (mentioned above) which measures 48mm x 32mm and is likewise based on the i.MX8M Mini SoC.
