No normal sized HDMI sucks, I don't want to buy another adapter, aside from that this looks really cool, can't wait to get one

Every year we upgrade our autonomous sailboat controller to the latest Raspberry Pi. This year we face a situation to choose from Jetson Nano and RPi 4. Even the decision is hard to made, now is an exciting moment for robot makers.

Damn I remember back when the TK1 was the new kid on the block. The nano looks awesome, I'm gonna have to get my hands on one of these!

>Are you still using VideoCore? >Yes. VideoCore 3D is the only publicly documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less. This stated intention and rpi.org's actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1] Secondly, why was rpi.org caught adding DRM chip…

As a previous line manager one said to me “yes, and I want a pony”. That they want to be more open does not mean they are currently fully open – in fact, it requires them to not yet to be fully open. Their primary goal (last I checked) is to be cheap, being fully open is at the very best their secondary goal.

That doesn't follow. Firstly, I don't think I've seen any other SBC vendor fail to publish full schematics. This is a peculiarity of rpi's offering.

Secondly, nobody is forcing them to add DRM chips to anything. That's not something that can be written off on "a contractual obligation made me do it." They did it of their own will.

My first reaction to the specs: Pros: + USB 3: Very nice! Finally a pocket-sized, fast USB host. + Dual HDMI: Could be useful as a projector computer. + 1.5 GHz: Good, it might be fast enough for some real work. + Gigabit Ethernet: Excellent for those using it as a NAS. + USB-C for power: Not surprising, it's the standard now. Cons: - MicroHDMI: Incompatible with the 800x480 HDMI 3.5" screen [1]. Also different again…

Con for me is still SD storage :-( At least now an SSD over USB3 should be reasonably fast

What a surprise! Didn't they say RPi4 is coming next year?

> In the past, we’ve indicated 2020 as a likely introduction date for Raspberry Pi 4. We budgeted time for four silicon revisions of BCM2711 (A0, B0, C0, and C1); in comparison, we ship BCM2835C2 (the fifth revision of that design) on Raspberry Pi 1 and Zero.

> Fortunately, 2711B0 has turned out to be production-ready, which has taken roughly 9–12 months out of the schedule.

According to their article they finished after 2 revisions rather than the predicted 4-5.

1) They make a low cost computer where they've put significant work into making it more open software wise.

Their revenue stream is through the sale of their hardware, why do they need to allow people to make clones?

2) Maybe it's to do with the terms in which they get the camera module?

I don't know but I don't see them selling the camera as interoperable.

Your comment just seems to exemplify the phrase:

"No good deed goes unpunished"

They do something good but freeloaders just turn up and demand more.

C'mon, a mini-hdmihdmi cable is 50kr ($5), surely you can just buy one and be done with it, no adapter needed.

> 4K!

I'm very excited about these upgrades too (especially GigE), but as far as I can tell nothing on this news page specifies whether the Pi will also support HDR output as part of the 4K upgrade. That's most of the practical benefit of 4K - that 4K releases tend to come with HDR10 or DolbyVision support.

Anyone know if we can expect HDR output to work? If I knew it supported that I'd be purchasing one right now to upgrade my media center from my current Pi 3 setup.

Even the tech specs page says nothing about 10bit decoding, which is required for most real world 4K HEVC video.

> H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
