The K210 was released last year by crypto-mining chip maker Canaan and sipeed build devboards and a python layer that work very well. The dev boards are cheap and well made, including screen and cheap ov2640 camera, it's plug and play, almost.
PROS:
- small
- power efficient
- crazy good value for the price
- fast enough to do mobilenet v1 at 28 fps
- very decent documentation and API especially for a 6 month old hardware
- very responsive dev team that'll help you
- NN in keras means easy to design your neural net and train it
- two builds of the python firmware include openMV!
- include a neural net accelerator, hardware FFT and can handle a 7 microphone array for sound location!
- linux heavy so you'll have to setup a lot of things right, the easy way: https://github.com/laurentopia/Learning-AI
- toolchain somewhat convoluted, requires a lot of setup also but once it's working it's a few clicks to convert from .h5 to k210 native format
- toolchain a bit green so you may run into problems but there are people to help on the telegram channel
If you're seasoned, get it, it's fun and fast.
