as said, the pi0 is that cheap that every adapter is going to cost more than it LOL

Is there any diagram or spreadsheet that explains all test-points on bottom side?
Well in essence I am interested if there is any audio out (and why there is none alongside reset and tv out headers), and what is that unpopulated 8 pin thing on bottom side.

The Swag store, Pimoroni and others are selling the Zero with an (optional) kit with various connectors and adaptor cables for an extra few quid.

Only can buy ZERO with kit therefore goes up to around £12.50 from CPC UK

They've done it again. Those glorious nerds have done it again.

A "full" computer for $35 was an incredible achievement. Getting the price down to $25 for the Model A was a big step forward. They've now shrunk the price to $5 and you still get the same spec as the original Model A - better than the Model A in fact.

This really is a staggering achievement, I've no other words to describe it.

It's a mini-HDMI Dougie, the Hudl cable won't do.

I know it's obsolete tech, but it would have been nice to have had microHDMI & Lapdock compatible socket placement. Was this ever considered, as the microUSB power in seems to be bang on located where a Lapdock microHDMI sits?

All said, another ground breaking, landmark product from Pi Towers!

Another competitor has been blown away, wonder how this will effect the MicroBit ?
I think it's the perfect accompaniment to the Micro:Bit. We had a play with micro:bits already at my school.

My best analogy is that they are like Arduinos but with built in internal sensors and very child friendly programming interface. It's not a full blown computer like the pi.

So the microbit can be programmed via the pi zero (using the offline compiler if you dont have WiFi) but the really really reeally cool thing is that the microbit pins should be directly compatible with the raspberry pi zero GPIO header. (The microbit runs off 2X AA batteries, is 3V) (I'm wondering if you would be able to get away with just sticking a bit of wire into an unpopulated GPIO header hole and secure it on with blue-tak)

That means pi zero + microbit = low cost full blown computer with A2D, accelerometer, compass and temperature sensor.

It's MINI HDMI not Micro, which is unfortunate as I have a micro cable already.

Looking for micro usb hubs, am I correct in thinking I need to avoid any of the USB OTG versions as they cross over the cables?

Ah I think I've got one of those in my box of cables.

Why do we end up with so many "standards" for cables and connectors. Why can't it be simple?

BTW, I wonder how many folk will solder in female sockets (like an Arduino) on the header rather than the male pins?

Bare conducive is also coming out with a board with audio:
http://www.bareconductive.com/news/intr ... rd-pi-cap/

Is this the first Pi without a camera MIPI port, or can it be soldered on ?

Still in shock about the price point though, and was tempted to empty the shelves at tesco, but just bought one :D

I was wondering that too, looks like either a USB thing or HDMI, but a wild guess. Just need to find a micro usb wifi dongle for a neat tidy connection. :)

An impressive bit of design, well done RPF

How long before someone asks what they can cut off to make it even smaller? :(

Having watched the Raspi TV video, it actually needs USB OTG, so at least I've got one of those cables about.

Yes, no. There's no pads for it.

I was also wondering about that.

8 pins suggest not USB or HDMI.
No Phy chip so not Ethernet (that would be 8 pin)

That 8 pin thing is probably some sort of jtag, but info on other test pads would still be highly appreciated.

I know there are alternatives to the missing audio outputs, but I'd just like to know: are the two PWM outputs which are used for audio on the other Pi models accessible on the Zero? So long as we can make connections to them, via solder pad or GPIO pin, we can add an RC filter to have audio work in exactly the same way (i.e. use the same SD card image) for just a few cents of hardware. If not, I'll understand - for $5 you can't have everything, and as everyone has said, this is the most awesome IoT device out there at this incredible price.

I'd assume it was like the 8 pin test connector on the underside of the HDMI on the 2B (not having looked at the pictures or actual board yet)

Of the 8 pins, two are what I suspect is ground, another goes to the RUN header. Some sort of alternative power input, maybe a rechargeable battery where the unpopulated U13 is the charge controller?
