Can you deliver RPis without any connectors soldered?

Thu Jul 10, 2014 7:12 am

Hello,

Would it be possible to have several RPi delivered without any connectors soldered on (USB, Ethernet, HDMI, etc.)? For embedded robotics projects the connectors are practically useless and add bulk.

Thanks,

Alex.

As the Pi A & B are made on a production line, it is more expensive to not put on the connectors, though it appears it is feasible to un-solder them yourself !

The Pi Compute Module may be worth investigating though

Take what I advise as advice not the utopian holy grail, and it is gratis !!

Fruits right - custom runs through the production line cost a hell of a lot, so something with less connectors would be very expensive.

Thanks all the the comments. Sincerely the CM seems a little expensive at this moment and also restrictive on the Linux distro supported. But having support for 2 cameras is quite an interesting feature as this opens the door for some cool stereo vision processing.

Regarding the connectors - I remember seen in a film some time ago that they are actully mounted by hand in a second step in the production process (after the SMDs are soldered). Maybe someone knows someone at the Sony factory that can confirm if indeed there are boards without connectors at one point in time that can be taken off the production flow. Of course they might have not been fully tested - but sincerely I heared the fault ratio is extremely low so I would be happy to take the chance with a half tested board.

I'm afraid it's just not going to happen - everything is pretty automatic I believe - it has to be to produce the numbers required (over 8k per day).

Note that the CM (by itself) will be around $30 - the IO board is 'expensive', but not if you make you own. I expect there will be cheap mounting boards available at some point.

And the distro on the CM is the same as the Raspi itself. It is basically the same device in a different form factor.

It's a common request, but nowhere near enough to do a custom run on the production line.


Easy enough to take off the analogue video and audio connectors:

A 3rd party company could desolder connectors and sell " depopulated Pi ", but would you pay extra ?

If someone placed an order for 8,000 or 1 day's worth of production could it be done?

Probably (But I don;t work for Sony/RS/Farnell)

That would be $280,000 please.

Finding 8000 people who want a fairly useless board would be the difficult bit.

Also, much cheaper to get a base board for the CM designed and built which has the features you want on it.

:D

At those volumes Chancelor could probably get quite a nice price on Compute Modules & custom carrier boards.

I would advise using loads of flux and a rework station :).
I would be quite interested to see which kind of "custom", compute module-based Raspberry Pis people come up with!

Actually no, it costs much more to change the production run than just not populating a set of connections...

The problem is it changes the way the hardware is tested and therefore would require extra work to do it...

It also requires that someone reprogram the machines for the SMT placing

And it requires that James or I have to do some work... Add all that together and you end up with a fairly big expense, especially when you consider all the other work we're trying to do at the moment!

Is that in reply to me?

I meant that buying 8000 stock compute modules, with stock firmware, and 8000 of his own designed and sourced carrier board might get to a similar price to a one-off model B.

The OP mentions "embedded robotics projects" which might not require anything special to use CM.

True, coz the first thing I'd have to do is solder something on to it :!: :idea: :lol: :lol: :lol:

I think it's aimed at my 'probably' comment a bit further up. Gordon doesn't do quotes!

I agree - much cheaper to build your own CM board.
