At the Raspberry Jamboree, on Friday 28th Feb 2014, I spotted a nice little seven inch screen, that looked a lot like the screen from a 2012 model Nexus 7 (but a bit grainier as the Nexus 7 has a higher pixel count).
Then I spotted the PCB with the Raspberry Pi Foundation logo on it, and realised it must be the official DSI screen prototype. Sure enough, it was connected to the DSI port. I turned round and saw Andrew Laing, Global Manager for Raspberry Pi at Farnell. He told me he’d been displaying it at Embedded World and had come straight from there. He didn’t have any pricing info to share, but Liz Upton recently tweeted a target price of <$70 (plus shipping and taxes, I assume).
I’m Giving It a Nickname
In the absence of an official name, for ease of comparison, I’m going to nickname it DSIPi. So here’s a photo of DSIPi…
When’s DSIPi due?
I know from HDMIPi experience, that nobody wants to be pinned down on things like this. ‘A few months’ is the best we can get.
So How Do I Feel About DSIPi w.r.t HDMIPi?
I feel great about it, and I want one. We knew before we even began HDMIPi that this was planned. Dave spoke to Eben back in May 2013 and I went to see Liz before we did the KickStarter. It made good sense to us to be as open as possible in order to avoid duplication. We want to work with the Foundation, not against them. We’re all on the same side. :)
They’re Different Animals
The two screens offer something different. DSIPi attaches to the DSI port and HDMIPi to the HDMI port. You can use them both at once on the same Pi. In fact, there will be a lot of applications for using both together.
Here are the specifications that I managed to find out. DSIPi has…
- 10 point capacitive touch.
- 7 inch LCD
- DSI connector
- 800 x 480 pixels
- works only with Raspberry Pi (as far as I know)
I haven’t yet heard anything about enclosures/cases for DSIPi. I don’t know if there will be one, or if, like the Pi, it’ll be left to third parties.
The comparable HDMIPi data is…
- No touch, but may be an optional extra
- 9 inch LCD
- HDMI connector
- 1280 x 800 pixels
- Pibowesque surround
- Works with any device with HDMI output (HDMI 1.4)
HDMIPi Meets DSIPi
As I had the HDMIPi prototype on me, it would have been positively rude not to have introduced them to each other. After all, they’re family. So here’s a rather hurried shot of DSIPi and HDMIPi together…
I’m kicking myself for being in a hurry now. It would have been great to fire up HDMIPi and get them both running from the same Pi. (Gordon’s just told me that the software on that one didn’t support it yet, so it wouldn’t have worked anyway.)
Musing out loud with Charlotte Godley, Ryan Walmsley and Matthew Timmons-Brown, we came up with the idea of using HDMIPi, DSIPi and Texy’s 2.8″ TFT or PiTFT all at once on the same Pi. Now that would be cool. It has to be done.
