This software allows M5StickV / Kendryte K210 / Sipeed Maix MicroPython users to publish images from their device to their local network.
The K210 features an onboard neural network and computer vision accelerator chip, but often is packaged without wifi.
Only the low level connection code works (and is useful to transfer images). Webserver part missing (but easier).
The software connects at 115200, switches to 1.5mbps, and then begins downloading images.
It shoves raw Python commands into the remote MicroPython REPL. That way you don't have to load any firmware or transfer any files into the bootloader / flash / etc.
The data is encoded using (u)binascii.hexlify().
