This is an odd little board. It has 2 RISC-V cores (different clock rates) an ARM core (A53) and an 8051 MCU core.
With the low price it could be interesting as a platform in an educational setting perhaps.
- Levitating 2y agoAnd 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).
