MaaXBoard 8ULP SBC leverages NXP i.MX 8ULP Cortex-A35/M33 SoC for Edge audio and HMI applications

Avnet MaaxBoard 8ULP will be one of the first single board computers (SBC) based on the new NXP i.MX 8ULP Cortex-A35/M33 processor designed for Edge audio and HMI applications, and featuring NXP’s EdgeLock for device-to-cloud security.

The board will come with 2GB RAM, 32GB eMMC flash, a MIPI DSI display connector, a MIPI CSI camera connector, Fast Ethernet and WiFi 5 connectivity, a digital microphone, and a 3.5mm stereo audio jack, and provide expansion capabilities via a 40-pin header for Raspberry Pi HATs and a 16-pin Shuttle Click header for MikroE Click add-on boards.

MaaxBoard 8ULP Block-DiagramThere’s little information about software at this time, except the board will be running Linux. What the company calls the LPAV domain (Low Power Audio Video) has a HiFi 4 DSP (600 MHz) core
to support advanced audio, machine learning, and sensor applications, while the Fusion DSP (200 MHz) core for low-power audio/voice use cases such as wake-word detection.

The MaaXBoard 8ULP board will be offered with optional 7-inch MIPI DSI touchscreen display, 5MP MIPI CSI camera, and/or 5V/3A USB Type-C power supply. Avnet expects customers to use the board for Edge-AI applications, machine learning, secure entry access-control systems, inventory and asset monitoring,  surveillance cameras with recognition, Smart Home appliances, and industrial robots.

Avnet has not provided pricing information for MaaXBoard 8ULP SBC because it is an early announcement that was made for Embedded World 2022, and the board is only expected to ship in Q1 2023. Additional information may be found on the product page.

That’s a SoM with a Pi-sized carrier, both look really neat, and I wonder if one could be able to order them separately?

I hate these 5V high current USB-C dumb chargers, just implement PD, OK?
