Got a free Saturday and a computer-vision idea you keep shelving? The usual choice is annoying. An ESP32-CAM runs out of headroom the moment you ask for anything clever, and a Raspberry Pi drags an operating system, longer boot times, and extra power draw into a job that should be simple. XMOS built XCORE-VISION to sit right in that gap, and it is the kind of board worth clearing a weekend for.
What XMOS built
XCORE-VISION is a small embedded vision platform around the XCORE.AI XU316 multicore microcontroller. It grabs camera data and runs AI models locally in real time, with no cloud round-trip. The 8-megapixel sensor is already on the board, so you can start classifying objects or spotting faces the moment it lands on your bench. XMOS has demoed MobileNetV2 and YOLOv8 running directly on the chip for object classification, face identification, and logo detection.
What you get for the money
The XU316 leans on hardware-level parallel processing and deterministic timing, so you know exactly when each operation fires. That matters for robotics or industrial monitoring, where one late frame is a real problem. Two digital MEMS microphones sit next to the camera, so a project can react to what it sees and what it hears at once. Filling out the board: 64 Mbit of QSPI flash, a button, an LED, 3.3 V I/O for external hardware, two Micro USB ports (one for debug and power, one for USB data), and an integrated XTAG4 interface so you can flash and debug without buying a separate programmer.
Worth a weekend?
XMOS plans to open-source the schematics and firmware once boards ship to crowdfunding backers, so a Sunday spent reading the application notes now sets you up to move fast later. If you have been stuck between an underpowered camera module and an overkill Linux box, this is the middle path to sketch out on paper this weekend.
