Edge AI looks like going to be the next big things. In this blog post, I am going to introduce a very cheap and yet power AI chip based on Kendryte K210. K210 is based on open source RISC-V instructions set. According to Wikipedia, RISC-V started in 2010 and in the recent 2 years, actual chips are produced with prototyping boards.
A few China companies have started to build prototyping kits around this chip. One of these company is SiPeed. They have produced a few form factors of prototyping board and I have gotten hold of the Maixpy GO board.
- 2.8 inch touch LCD
- TF card slot
- RGB LED
- Rechargeable battery
- Powered via USB C. The USB-C also act as Uart for transferring of codes and flashing of firmware.
There are a few ways to program the kit, micropython, Arduino IDE or Platform IO. For micropython, there is Maixpy IDE which is a port of OpenMV IDE.
Sipeed also has 2 interesting peripherals, microphone array and binocular camera. The subsequent post I will write more about the 2 peripherals.
Looks like this is going to be a very interesting AI and IoT platform. I will follow-up with more write-up especially the AI portion. Stay tune!
Update: Transfer Learning using mobilenetv1 in colab to generate kmodel file.
