First i.MX8 QuadMax SBC breaks cover

Mar 14, 2019 — by Eric Brown — 1256 views

Seco announced a 3.5-inch “SBC-C43” that runs Linux or Android on an up to hexa-core i.MX8 with up to 8GB soldered DDR4 and 32GB eMMC plus WiFi/BT, 2x GbE, 3x USB, HDMI 2.0 in and out, 2x M.2, and -40 to 85°C support.

We’ve seen about a half dozen compute modules based on the high-end, Cortex-A72 enabled i.MX8, mostly recently including Variscite’s VAR-SOM-MX8 and SPEAR-MX8. Seco’s 3.5-inch SBC-C43, however, is the first SBC we’ve encountered. The 3.5-inch SBC offers soldered memories and optional industrial temperature support. It’s designed for biomedical and medical devices, digital signage and infotainment, edge computing, industrial automation, IoT, smart vision, and vending.

The SBC-C43 offers NXP’s default Yocto Project Linux stack, as well as Wind River Linux and Android. The SBC supports all three flavors of i.MX8, including the QuadMax with 2x Cortex-A72 cores and 4x Cortex-A53 cores, the QuadPlus with a single Cortex-A72 and 4x -A53, and the Quad with no -A72 cores and 4x -A53. No clock rates were listed but Toradex’s Apalis iMX8 module clocks the -A72 cores at 1.6GHz and the -A53 cores at 1.26GHz.

All three models also feature 2x Cortex-M4F real-time cores and 2x Vivante GPU/VPU cores. The QuadMax integratess the GC7000XSVX GPU while the other two models have the Lite version. Video support is the same, however, with 4K30 decoding and the ability to drive up to 4x displays at once. Note, however, that you’re sharing the 4K resolution between the different outputs.

The SBC-C43 supports up to 8GB DDR4 and up to 32GB eMMC, both soldered to the board for greater reliability. There’s also some boot flash, a microSD slot, and SATA support via the M.2 Key B slot, which can alternatively load a modem card or other M.2 PCIe add-ons.

There’s also a non-storage ready M.2 Key E slot and an accompanying SIM card slot. The SBC supplies 2x GbE ports and a WiFi 5 (ac) with Bluetooth module plus internal antennas.
