(BTW will a VGA Converter that draws power from HDMI Ports Work? This Box can draw directly from the Pi and I would love to use less power plugs.)
If you have a B+ then it will provide enough current to the HDMI port for cable powered adapters to work, on a B its a bit iffy, but no longer so on a B+
So I can use it to power a converter box? This takes 5V. (The AC adapter says 2.5A. I am a bit worried... (xd)
what AC adapter are you referring to?

No HDMI=>VGA converter box will need 2.5A! and even a B+ would not be able to supply 2.5A to it.

Just because a power supply can supply 2.5A does not mean that it will always output 2.5A! The load determines how much current it will draw, and the power supply can deliver it, up to a maximum (of 2.5A in this case).

Got it working, just don't connect it to a speaker, a wifi dongle, bluetooth dongle, USB -> PS/2 keyboard&Mouse without powered USB hub, HDMI-VGA converter, with a 0.7A power supply :D

Also, the power supply says D-Link. It's as generic as a generic microSD.

What is a micro SD card ? Is it same with an Android phone micro SD card ? What is a full size micro SD card ?

Does all raspberry versions (A A+ B B+ and version 2) use same micro SD cards ?

Where can I see correct information ?

A micro SD card is exactly the same as the microSD card I use in my Android phone

There is only one physical size of SD card and that is about 11mm x 16mm. They are available in many capacities.

You get full size SD (24mm x 32mm) cards or micro SD cards. There is no "full size micro" SD card.

The A+, B+ and B2 use micro SD cards.
The A and B use full size SD cards, or microSD cards in a full size adaptor.

Great information has been posted, in that post for each and every thing you provide a description as well an suitable image, it's looks like a project presentation. Great work

The camcorder cable which is reported above in the post as tested and able to work (visit: http://www.amazon.com/Fosmon-Technology ... B00HND2FW8), actually doesn't work. The sleeves on a standard camcorder cable read in the following way (from the base to the tip): right audio, ground, video out, left audio. The sleeves on the cable by Fosmon Technology, which I purchased on amazon.ca in May 2016, are positioned in the following way (from the base to the tip): ground, left audio video out, right audio. The big issue is the location of ground. Please adjust this post to warn people about buying this product.

Hello there..
We would ask about device RASPBERRY PI 1 MODEL A+ if it can work between internet of things and amazon ec2 cloud and consul ( an open source tool) or not ? Because we have a project and we looking for the suitable device that can make amaze communication between those clouds.

cleaned up some pictures (the ones that couldn't be reached anymore) replacing them with new external sources, preferably from a source like wikipedia. Also added the PI Zero-W. the pictorial buying guide needs regular maintenance. The AV cable shown now is from kiwi-electronics, and is guaranteed to work on a PI with an AV output connector. I also listed some places (adafruit and kiwi-electronics) where you can find AV cables guaranteed to work.

When talking about the power supply, this guide doesn't say what happens if the power supply is larger--for example 3 amps, like this one. https://www.ebay.ca/itm/112770796970?var=413215204786

I figure it isn't a problem, but am curious. It wouldn't waste the extra amps, right?

As said before if a power supply says something like 3A, it means that it can deliver 3A (at maximum) but the device it is connected to it will just draw what current it needs, nothing more.

The mini USB (the fourth from the left) is the wrong one. It’s larger and looks like a trapezoid with its sides pinched in. The micro USB (the third one from the left) is the correct one
Hi - I think this should read - the ones from the Right (not the left )

Hey nice guide,
but i still got a question. Is the Raspberry pi 3b+ working with components that are made for the Raspberry pi 3b series? I would like to attach a display but iam not able to find one who is compatible with the 3b+ series.

Best regrads and thanks in advance
Lenny

I started with Raspberry Pi today. Thanks for some clear and detailed images on this topic
I have confident to start with my own board now

Yes, although the PI3B+ needs a 2.5A power supply.

Hi. I’m new to Raspberry Pi and need to work out what I need to get started. The pictorial guide has been very useful so far. My plan is to use the pi to control and monitor basic inputs/outputs. Outputs to switch on/off a few ordinary relays. Inputs to monitor whether a circuit is open or closed. I need 5 outputs and 2 inputs. (This is my starting point. I hope to move on to something more sophisticated later.)
I gather that the pi will do this okay but I reckon there must be some sort of interface required to connect my circuits to all those pins.
So, in addition to the basic kit, what do I need to buy?
Also, is different software (operating system) required?
Any simple guidance would be gratefully received.
Thank you.

UPDATE
I’ve bought a Model 3B+ and a SD card with OS. I have also found a HAT that appears to fit onto the pi’s pins and converts them to screw-down terminal connectors. I hope I’m on the right track.

I see this wonderful guide was provided 2012.
Is it up to date in relating to specifically what I "pasted" below?

"If your monitor only has a VGA Connector you need to buy a cheap HDMI to VGA adapter. It is not possible to buy a cheap HDMI->VGA Cable. If you see a cable that is VGA on one end and HDMI on the other it will not work."

Most humble regards and sincere thanks for your guidance and direction to a "noobie".

The fact the cheap HDMI->VGA cables are unusable hasn't changed.

The HDMI output of all Pis to date use the same interface (Pi Zero uses a smaller connector, but same specifications).

HDMI to VGA cables (not converters) rely on a non-standard HDMI interface that can provide a VGA signal.

This is what I used to use to convert HDMI to VGA, works well.
