BeagleY-AI SBC features TI AM67A vision processor with 4 TOPS AI accelerators

The Foundation’s BeagleY-AI is an open-source hardware, credit card-sized SBC powered by a Texas Instruments AM67A quad-core Cortex-A53 vision processor with various programmable blocks capable of delivering up to 4 TOPS for AI algorithms.

The board ships with 4GB RAM, relies on a microSD card slot for storage and OS booting, implements gigabit Ethernet, WiFi 6, and Bluetooth 5.4 connectivity, and can drive up to three displays via micro HDMI, OLDI (LVDS), and MIPI DSI interfaces. The BeagleY-AI also comes with two MIPI CSI camera interfaces, four USB 3.0 ports, a USB Type-C port, and a 40-pin GPIO header for expansion. We can also see a 16-pin PCIe FPC connector that looks somewhat similar to the 20-pin PCIe connector on the Raspberry Pi 5 but officially supports PCIe Gen3 x1.

The board runs a Debian image with the XFCE desktop environment. Since the BeagleY-AI is open-source hardware you’ll find the (Altium) hardware design files on OpenBeagle and the documentation page is up, but currently empty, although a quick start guide (PDF) is already available. There’s currently no public datasheet or even a product page for the AM67A/J722S SoC. This can be easily explained as the Foundation was given early access to the upcoming vision processor and all I could find on the Texas Instruments website at the time of writing was an evaluation board for the AM67A and pin-compatible chips.

But there’s still time since the BeagleY-AI will only become available in June 2024 at a fairly good price tag of $70. You can already pre-order your board today on Element14 or Seeed Studio. It’s not the first SBC from BeagleBoard with an AI accelerator, as the company introduced the BeagleBone AI-64 in 2022 with an 8 TOPS accelerator and the BeagleV-Ahead powered by a TH1520 quad-core RISC-V processor that embeds a 4 TOPS NPU. More details may be found on the product page.

“an open-source hardware, credit card-sized SBC powered by a Texas Instruments AM67A quad-core Cortex-A53 vision processor”

Really? Is that true?? An open-source
AM67A quad-core Cortex-A53 vision processor?

Thanks for the clarification.

(I think Intel owns the IP for USB too.)

Has TI changed their mind about locking out C7x away from customer code?
