Sipeed Maix Bit is a small board (Arduino Mini sized) from SeedStudio that incorporates the new ML optimized Kendryte 210 chip.
You can get it from the vendor: https://www.seeedstudio.com/Sipeed-MAix-BiT-for-RISC-V-AI-IoT-p-2872.html or from Amazon: https://www.amazon.com/dp/B07SDLHKG4 . For about $25 you get a bundle with the board, a camera and a 2.4 inch LCD. I do recommend you get the bundle as it will all just work together and make it easier to debug.
Assembly
Insert first the camera cable. To insert it first raise the black tab on the right of the connector (as seen in the picture above), insert the cable and then press down the tab. Screw in the camera with the provided screws. I placed the white plastic washer in between the board and the camera and then inserted the screws from above. Connect the LCD cable the same way. The wires go down and the LCD screen will face the same direction of the camera.
Both the ribbon cables goes in the white part of the connector which is confusing since in earlier versions in was reversed.
Testing
These instructions are for connecting the board to a Windows computer.
Power the board with a USB type C cable. It doesn’t have a separate power connector. You should see the screen powering up.
Documentation is in Chinese but you can translate it with Google Translate. There is an “English” version of the documentation but it is incomplete and it is translated by Google anyway.
To get started go to:

For USB drivers download zip from the manufacturer of the USB chip.

Unzip and run setup.exe.
I had some errors before. I probably installed a different driver and it only worked once I uninstalled it.
Connect the board to the USB of the computer (remember you will need a usb-c cable or use an adapter)
Check the usb ports in the Device Manager\Ports
It was COM4 for me (there was a COM5 added as well but most interactions happen with the first port)
Start putty ( https://www.putty.org/ ), select Serial, enter COM4 (or whatever COM was added for you) and baud 115200 and connect.
Type help() and Enter, you should see some response. That indicates that the connection and the board is working.
You can type commands one by one.
I will post instructions on how to run some scripts and how to do training for your own ML models.
