MaaXBoard OSM93 – Business card-sized SBC features NXP i.MX 93 AI SoC, supports Raspberry Pi HATs

MaaXBoard OSM93 is a single board computer (SBC) based on a Size-S OSM module powered by an NXP i.MX 93 Cortex-M55/M33 AI SoC and offered in a business card form factor with support for Raspberry Pi HAT boards through a 40-pin GPIO header and mounting holes.

The board also comes with 2GB LDDR4, 16GB eMMC flash, MIPI CSI and DSI interfaces for optional camera and display modules, two gigabit Ethernet ports, optional support for WiFi 6, Bluetooth 5.3, and 802.15.4, three USB 2.0 ports, and two CAN FD interfaces with on-board transceivers.

The MaaXBoard OSM93 development kit is supported by a Yocto-based Linux board support package (BSP) and a range of example designs to help developers get started. The company also offers optional accessories such as 5-inch and 7-inch MIPI-DSI LCD touch panels, a 5V/3A USB-C power supply, and an M.2 wireless module.  The original MaaxBoard was first introduced in 2019  with an NXP i.MX 8M processor and other versions have come out since then with the MaaxBoard Mini, MaaxBoard Nano, MaaxBoard 8ULP, and MaaxBoard RT all based on other variants of the NXP i.MX processor family.

Users will be able to get some support on Element14’s forums, and I also noticed two GitHub repositories for the new board: one for an information hub (currently empty) that should provide user and developer getting started guide and links to the BSP, and another for demos with currently a fitness demo (empty) and a web server written in Python.

As the status of the documentation already implies, the MaaXBoard OSM93 (part number AES-MAAXB-OSM93-DK-G) is not available yet, but Avnet plans to launch it in Q2 2024, along with the i.MX 91 (OSM-SF-IMX91) and i.MX 93 SOMs (OSM-SF-IMX93), and the accessories. Eventually, more details will surface on the product page including purchase links. Avnet probably announced the board early because they will be showcasing it at Embedded World 2024 on April 9-11 in Nuremberg, Germany alongside other development boards from the company.

  1. I think it’s the SoM which is business-card sized, not the SBC, which seems to be roughly in RPi size. Unless they have very large business cards of course 🙂

    1. Huh, I’ve also always assumed the RPi is bigger than a business card. It looks really strange to me seeing them side-by-side. Maybe it’s because I’m so used to looking at Pi’s up close?

      1. No, it’s because they’re thick due to ports etc and when we see them, the perspective makes them look bigger in the two dimensions.
