Sold out already. :- )
I want to see what Espressif, SiPeed, or some other vendor manages to do with RISC-V. I'm currently prototyping an A2DP vendor codec extension for Opus using an ESP32 board, and it is pretty painless. Bluetooth is the high value bit in my opinion.
- ac29 8y agoThe module without WiFi is in Stock (and is the $8 model, the WiFi is $9). https://www.seeedstudio.com/Sipeed-MAIX-I-module-w-o-WiFi-1st-RISC-V-64-AI-Module-K210-insid-p-3210.html https://www.seeedstudio.com/Sipeed-MAIX-I-module-w-o-WiFi-1s... There's also a dev board, which is probably much more useful than these bare modules. Unfortunately also out of stock: https://www.seeedstudio.com/Sipeed-MAix-BiT-for-RISC-V-AI-IoT-p-2872.html https://www.seeedstudio.com/Sipeed-MAix-BiT-for-RISC-V-AI-Io...
- mrmondo 8y agoAh I’ve had really good experiences with SeeedStudio too, ordered plenty of things over the years - dangerous site for me to visit when I have money ;,)
- agumonkey 8y ago13$ for a rpi zero w like thing.. not bad
- tyingq 8y agoI think "esp32 like thing" is probably a closer comparison.
- agumonkey 8y agoThat thing clocks a 400MHz out of the box and has coprocessors .. I'd also guess that risc-v isa is more performant than esp32's one (super wild guess). Let's say it sits in the middle :)
- yjftsjthsd-h 8y agoThe distinction to me is software; if it runs Linux or such, it's a computer. If I have to provide "firmware" then it is a microcontroller.
- therein 8y agoThat distinction is getting blurrier and blurrier every day with the ability to flash firmware to some MCUs such that they run Linux. :)
- milkey_mouse 8y agoIn my opinion the line to draw is support for a privileged mode/protection rings/memory protection. Anything without that can run μClinux at best, which isn't much better than an RTOS. Without process isolation an operating system isn't very "general purpose."
- justinclift 8y agoThere are Fedora and FreeBSD builds for RISC-V. This particular item seems to have only 8MB though, so not really in (most people's) "computer" realm. ;)
- dklsafhjskljfl 8y agoI view wifi on these devices as an anti-feature. Too often, they rely on MVP web services with limited security, and require a full TCP/IP stack, alongside CA-based PKI (meaning, an inherently limited lifespan). Not against a limited lifespan, but I really do like the model of a bridge device that communicates over wire or bluetooth, especially for consumer IOT - bt-based standards prevent vendor lock-in, for example.
- brucehoult 8y agoYeah, Espressif joined the RISC-V foundation, so it will be interesting to see if there is an ESP32 with RISC-V instead of Xtensa sometime soon.
- microcolonel 8y agoMaybe an RV64GC[V maybe] ESP64, with a bit more RAM. :- )
- Roark66 8y agoWhat a joke of a "release" why are all such products almost immediately out of stock. Do they make 20 units? They don't even bother to say on their website when if ever they'll have more units available. Imagine if you worked months to develop a product based on this chip and after all this work you can't use it because it is out of stock with no further info. This is why it'll make no sense to use such chips until they can be bought at digikey, mouser etc in serious quantities.
