two usb C ports on the top left for scale, currently trying to figure out how to build a linux image for it 🤷‍♀️

Cool, I’m excited to see RISC-V take off. How good is distro support?

not great tbh, there aren’t any distros that can output a video signal via hdmi, and you have to connect via debugging port or something like that (and many of them don’t boot at all)

to clarify, there are many images available, but myself and other people testing them out were largely unsuccessful

Who makes this? Is it essentially just a raspberry pi zero w but with a risc-v processor?

that’s a very big just 😄, but yes, it’s made by a company (which i suspect is just a single guy potentially lol) called mangopi

also this one has 1gb of ram instead of 512mb of rpi zero 2, plus it has usb C ports instead of micro usb

That actually sound pretty solid. I might need one of these >.>

it is 😎

they actually already have a prototype of a similar board that’s literally smaller than an SD-card 🤯

and it has 1gb of ram and a quad core cpu 😮 (though, as you can see, it only interfaces via pins, so it’s more of a compute module than a standalone board)

and i have to say that the support is still not great, like, you need to build linux a linux image yourself with third party tools and many things aren’t working yet, but overall, i’m very excited for RISC-V and its potential (and other boards from this company)

Can you please share details about this one?

Edit: if you are referring the following… it’s not RISC-V: https://hackaday.com/2022/04/01/mangopi-to-bring-a-sd-card-sized-linux-module/

yeah, it’s based on an arm cpu, sorry if that wasn’t clear from the comment

(they have two versions of many of their boards, one on arm and the other on risc-v)

they also have a board that’s about 40x40 millimetres, which i also have, but i can’t access it to showcase here unfortunately, but it was more of an early prototype: it only has 64mb of ram 😬, so not great performance, but cool for stuff like making your own OS 🤷‍♀️

This is cool. Fuck micro USB

yeah, honestly

it costs like a dollar more (even with the controller), and i’d happily pay that for any device, no matter the budget range, just for the convenience being able to use a single cable and not having to dig through a pile of micro usb cable 🤷‍♀️

Where did you buy it?! I can’t find anywhere that’s actually selling RISCV hardware outright. It’s all “preorder” or even “sign up and maybe we’ll let you buy one”.

thank me later 😎 (one in the pic)

https://www.aliexpress.com/item/1005004157984532.html

the other board (40x40 mm one) i mentioned was much harder to get, it’s only sold somewhere in china, and i only ended up getting it bc some guy messaged me on the forums and offered to buy an additional one and post it to me, and it took 4 months to get to me

(but it’s a earlier prototype, very little ram, so you’d probably want the one in the pic related)

Here you go: https://mangopi.cc/

And the model is this one I think : https://mangopi.cc/mangopi_mqpro

So cool i kind of want to get one but maybe i’ll wait for the next generation :D

You can also buy the Lichee RV and its dock, but it increased in price recently: https://www.aliexpress.com/item/1005003741287162.html

Details and installation instructions on https://wiki.debian.org/InstallingDebianOn/Sipeed/LicheeRV

yeah, and support and tooling is definitely better for the lichee rv…

currently trying to figure out how to build a linux image for it 🤷‍♀️

https://github.com/skiffos/skiffos already has support for two other riscv boards; maybe adding support to it for this one wouldn’t be too hard?

ty, i’ll check it out :)

I’d really, really love to own a RISC-V board like this one; but that must’ve costed a fortune. RISC-V hardware is not affordable yet.

@vitaminka

not really, this board costs ~20 usd, which is a fair price imo

I was expecting it to cost more than 50 USD, given that D1 is a SoC rather than a microcontroller, and a few months ago when I was looking at prices of RISC-V boards, the microcontroller boards I found were expensive AF.

the market is really small, so not only everything costs a lot to produce, the price hasn’t level out at all yet, so ppl will be selling these at wildly varying costs, which means you just have to look more

you’ve got everything from ~700$ development boards from sifive to inexpensive boards like this 🤷‍♀️

(if you’re curious, i left the link in another comment in this thread, as i said, the board is available for ~20$)
