I don't know much about it, but from a quick scan, it looks like some high-performance microcontroller, i.e. competing with some Cortex-M microcontrollers.
I think new Cortex-M devices will continue to evolve, with manufacturers releasing chips with more and more interesting peripherals and accelerators, and more and more RAM and Flash.
Personally I want to continue exploring and using Cortex-M devices from some of the well-known manufacturers, I'm not done yet, rather than something from a manufacturer I've never heard of.
But that's just me, and having said that, look at how popular ESP modules are, and they're very low-cost and were from a not-very-well-known manufacturer, yet they've been around for years,
people do a lot with them, so what do I know : )
The comparison with an STM32H743 is simply ridiculous - the two chips are quite different and aimed at different markets.
The STM32H743 does not cost $70.
The problem with RISC-V modules from China is getting decent documentation and tools - both are free and easily available from multiple sources for ARM processors.
I suspect that RISC-V is a coming thing - there is a momentum behind it, pushed by the Chinese corporate state (and others) so it may become a rival to ARM.
A dual 64 bit core core RISC-V processor is not really in the same class as Cortex M devices. If you are interested in further study it's worth reading :
and to get an idea of the money going in:
Have you used this thing or looked beyond the page you posted ?
Nup I was intrigued by the Cost point of the module and the claimed performance but did Not order YET due to the cost Although the Module itself is Cheep (850 INR) The usable Module Board costs about 2500 INR which given it comes with a LCD and Camera Module is slightly higher for me to try out.
I even found a Chinese FPGA Dev board that is like 1500 INR and boasts a ton of features, but al the docs is in Chinese and the Manufacture of the FPGA won't let me download the VDI file without a Chinese mobile no registration .
Doing some digging, I found that the product page is Non Existing but couple of links to GitHub Repos can be found
It seams to be based on Python.. ..
Will update if I find anything else.
UPDATE : Got the Documentation links ( and those are in English ) WoW, These people are serious. I think it may very well be something like ESP32 couple of years ago
They have FREE SDK available with Examples too.
Schematics of the Kit.
P.S> I May just order it
I was surfing the web and stumbled upon K210 Dual-core RISC-V 64bit Boards ...
another one Here and they pretty cheep for about 800 INR for the Module with Wifi ...
And these claim to have KPU(Neural Network Processor) inside, 64 KPU which is 576bit width, support convolution kernels, any form of activation function. It offers 0.25TOPS@0.3W,400MHz, and when you overclock to 800MHz, it offers 0.5TOPS. It means you can do object recognition 60fps@VGA.
Isn't that Coollll.....
and even BananaPi has then in their dev boards ..
Few details from the vendor:(Aliexpress)-

Awesome Features for a fraction of the cost ....
Anyone has used it ?
