I needed to create a 3D printed case for my Maixduino kit to make it easier to handle.  I came up with a quick prototype that I'll need to tweak but it lets me get started with testing.   The small cutout at the bottom of the case is for the external speaker connector.  I haven't provided the opening yet for the MEMS microphone which is located about halfway between the camera and the speaker connector.  It will be interesting to see how well the microphone will work embed ...
There are a few different tool flows that are available to program the Maixduino.  I previously used the Arduino IDE which allows reuse of existing Arduino libraries for common peripherals.   It appears that much of the Neural Network programming for the K210 KPU (knowledge processing unit) has been done using MaixPy (microPython).  So, I'm going to look at a tool flow that allows me to upload the MaixPy firmware and the network models and the Python programs.   The memory ...
I received my Maixduino AI Kit.  It was nicely packaged in a small plastic box.  The components were neatly wrapped in bubble wrap. The camera was pre-attached as seen in the lower right of the board so the only assembly required was to add a microSD card and attach the LCD panel cable. I had a couple of surprises getting started.  The first was that the Maixduino requires the microSD card to be formatted as FAT (not FAT32) and since the smallest one I had was 16GB I needed ...
