i.MX8M Mini SBC offers dual GbE with PoE

May 12, 2021 — by Eric Brown 655 views

Gateworks has launched a “Venice GW7200” SBC that runs Ubuntu on an i.MX8M Mini with up to 4GB RAM and 64GB eMMC. Highlights include 2x GbE with PoE, 2x mini-PCIe, MIPI DSI/CSI, and -40 to 85°C support.

Last year when Gateworks announced its 105 x 100mm Venice GW7300 SBC based on NXP’s i.MX8M Mini, the company said there would be three more Mini-based Venice SBCs, including a 140 x 100mm GW7400, 100 x 70mm GW7200, and 100 x 35mm GW7100. The Venice GW7200 has now arrived with the same dual GbE with PoE capability as the GW7300, but with one less mini-PCIe slot and no standard USB host port.

Unlike NXP’s i.MX8 and i.MX8M, the i.MX8M Mini lacks 4K video, but it is faster and more power efficient than the i.MX8M — its 4x Cortex-A53 cores are clocked here at 1.6GHz. There is also a 400MHz Cortex-M4 MCU.

Four Venice GW7200 SKUs are available: 1GB LPDDR4 with 8GB eMMC, 4GB LPDDR4 with 64GB eMMC, and either configuration with the addition of a GPS receiver with antenna connector. A GW7200 Development Kit version builds on any of these models with an Ubuntu BSP, bootloader, JTAG programmer, cables, and power supply.


As usual with Gateworks, there is extensive documentation, including 3D STEP files Customization services are available including the optional USB host port shown on the block diagram.

The Venice GW7200 is equipped with dual Gigabit Ethernet ports — one with passive PoE and the other with active PoE. Other features include a micro-USB OTG port, MIPI-DSI and -CSI, I2S audio, and a variety of serial and I/O headers.

The SBC is equipped with an RTC, watchdog, PMIC, and a 3-axis accelerometer. The roughly Pico-ITX sized SBC has a -40 to 85°C operating range and an 8-60V DC input.
