This board has onboard EMMC, wifi/ble and can run a full Linux. That is more of an rp 4/5 with an rp2xxx tagged on the side. It comes with their own arduino IDE installed too
It is kinda disappointing but I can see why Qualcomm wants to use the brand.
I'm speaking in a broader sense, comparing the variety of other Arduino boards like the Uno R3/R4. That wasn't too clear in the OP, sorry!
The concern I have with the $44 Q is it has 2GB of RAM and 16GB eMMC, and a processor that's probably between a Pi 3 and Pi 4 in terms of speed and IO (though 4nm, so probably much more efficient).
For $45 I can buy a Pi 5 with it's own built-in GPIO, PCIe, and a much faster SoC, though it lacks a few niceties like the Q form factor, the more efficient SoC, a realtime microcontroller, and a USB-C port with display out capabilities (I really wish Pi had that...).
Because Jetson is getting traction?
Yes, this new board is more of a Raspberry Pi replacement than an Arduino Uno replacement.
More specifically, I can see it trying to compete with things like those funny Chinese boards built around SoCs like SG2000. Those embed a Linux capable core, a small NPU, a camera interface with ISP and video codecs, and a secondary RTOS core for realtime control. Basically built for drones and simple robots. The caveat of those boards being: the documentations sucks, the SDK is wack, you get 3 example scripts and are entirely on your own outside that.
Qualcomm could be trying to branch into drones/robotics/etc with this move.
