A new Raspberry Pi, appeared end of November 2015. Called Zero, a break with the naming convention of A, B, A+, B+, Model 2 B. Reminds me a bit of the Arduino Zero 🙂
The specifications are close to the A+ with the following changes:
- (over)clocked at 1 GHz (called Turbo in raspi-config).
- 512 MB instead of 256 MB
- Micro USB connector instead of USB 2.0
- Mini HDMI instead of HDMI
- No Audio connector
- Composite video available on solder pads
- No CSI and DSI camera and display connectors
- GPIO connector not soldered on
This makes the Zero the smallest and cheapest Raspberry Pi but also the less equipped. But is essence it is just a first generation Raspberry. The price is set at $5 officially.The Zero behaves (with the right cables) as all the other Rasperry Pi’s. The OS is the same, the latest is Jessie november 2015, and runs fine. The only visible Zero addition is a new overclock option in raspi-config, called Turbo (1000 MHz). I tried also an older but uptodate Wheezy and that also runs fine.
I ordered two at the PiHut at launch day and was pleasantly surprised to get those, delivered very fast and at a price of £4. I also ordered the PiHut Zero Essential kit, which contains, in a nice can, micro to USB 2 adapter, a Mini HDMI to HDMI adapter and a large choice of GPIO connectors to be soldered in.
What makes the Zero special for me is:
- Price. Even if the local dealers in Europe will charge at least 3x the $5 price by including two cables and VAT and profit, it still is a bargain.
- Size. This flat design makes it fit in even smaller designs.
- Freedom in GPIO connections. See below for some examples how this can be done, the PiHUT understands this very well by including choices in the Zero Essential kit.
As a Raspberry Pi user from the beginning, I have plenty of cable solutions in stock. You can see what I prefer here. Now the Zero has a micro USB connector! Not a real problem since tablets, phones and even my latest notebook, the Asus T300-CHI, also only have these small connectors. Drawers full of micro cables and hubs therefore. So here some preferred USB devices I use now with the Zero.
