Forlinx’s SoM FETMX8MM-C contributes to the ever-growing list of tiny, Linux-friendly modules built around NXP’s i.MX8M Mini. This new board focuses on a variety of digital audio processing interfaces. Recent same form factor boards include MYIR’s MYC-C8MMX and Innocomm’s WB15. This new 56 x 36mm SoM FETMX8MM-C module runs Android 9.0 or Linux 4.14 on i.MX8M Mini. It has 2GB DDR4, 8GB eMMC, up to -40 to 75℃ support.

The new SoM FETMX8MM-C centers around the i.MX8M Mini’s specialty at digital audio processing. Other applications with this board may include facial recognition, video intercom, medical, and PDA. This board is powered by Android 9.0 or Linux 4.14 with Qt 5.10.

The SoM FETMX8MM-C is powered by the quad-core Cortex-A53 clocked at 1.8GHz. It also has 400MHz Cortex-M4 MCU and GCNanoUltra (for 3D) and GC320 (for 2D) graphics cores. Forlinx has mentioned that there are H.265 and VP9 decoders that can support 1080P@ 60Hz, which is 50% more efficient but bandwidth and capacity are only 50% of H.264.

The module primarily comes with 2GB DDR4 RAM and 8GB eMMC storage. Media I/O options are 4-lane MIPI-DSI and CSI Audio interfaces include I2S, AC97, TDM, PDM, SPDIF, and 4x SAI, as well as support for FLAC7.1 sound channel output and ring audio input.

The new SoM FETMX8MM-C has support for the Gigabit Ethernet controller and PHY support for 2x USB 2.0. It also includes a standard micro USB connector and USB 2.0 OTG (up to 480 Mbps). Other misc I/O includes PCIe, 2x SD/SDIO, 4x UART, 4x I2C, 4x PWM, 3x eCCPI, FlexSPI, and JTAG.
