And a TPU! Together with it's CSI this board is perfect for running image related neural networks like face detection.
> It has 2 RISC-V cores
These are separated though, with the default firmware the big core runs linux and the small core runs rtos.
They implemented a protocol called mailman to interact between the big (linux) core and the small (arduino/rtos) core.
The 8501 also implements mailman and this core can be used to wake up the others.
The usb-c connection is used for rndis so you can plug it in and immediately access it's internal network. But the usb-c connection can also be used to flash Arduino code (replacing RTOS).
Additionally the board supports 5 serial consoles via UART.
I now own a couple of these boards and the possibilities of what I can do with them seem endless. I also have the Duo S which includes an additional CSI lane, an ethernet port and a usb port (as well as color coded gpio pins).
With the low price it could be interesting as a platform in an educational setting perhaps.
