After the great success of Raspberry Pi (and its later update, Raspberry Pi 2), at the end of 2015, the creators of this mini-computer surprised us with the new Raspberry Pi Zero. It is a much smaller computer, with a power superior to First Raspberry Pi.
At raspberrypi.org they present a new member of the team, a new the Raspberry Pi Zero W model which is born to celebrate the five years of project and this time comes with WiFi and Bluetooth for only 10 dollars.
Raspberry Pi Zero is a computer that, as we have said, has many limitations, such as having to turn it into a tangle of OTG cables to make it work. Without going any further, last week we wrote an article in which we compared this mini-computer with the Orange Pi Zero, an improved version that improved many aspects of it, especially in connectivity.
We had already seen how the Raspberry Pi Zero, launched in November 2015, managed to reach consumers for only $5, but now, with the Cypress connectivity module CYW43438 (the same as the Raspberry Pi 3 model B), will allow to expand the number of projects we can do with this device, since you will not need cables. Thus we increase the list of ideas that we can program with a set of surprising specifications for its price.
It has a single core processor at 1 Ghz, half a gigabyte of RAM, Bluetooth 4.0, Wifi 802.11n, CSI connector for camera and mini HDMI outputs, microUSB and power via microUSB, also available a set of housings that we can see in the official post.
The hardware of the new Raspberry Pi Zero W is the same as the first model. Among its main components we can highlight:
- ARM Broadcom BCM2835 single core @ 1Ghz ARM CPU.
- 512 MB of RAM LPDDR2.
- Two micro-USB OTG ports
- Micro-HDMI output.
- Micro-SD card slot.
- Without GPIO base (you have to put the pins apart)
However, this new model includes a wireless connectivity chip that gives the device Wi-Fi 802.11n and Bluetooth 4.0, greatly improving the possibilities of this micro-computer and allowing us to have it fully working, even using the keyboard using the HDMI cable (Even if you do not control it remotely) and the power cable.
Here you have it on video:
With this new device we can connect keyboards via Bluetooth, for example, leaving the USB port free to increase the possibilities of our project like if we consider in many occasions of using Raspberry Pi in small vehicles such as skates. There is nothing better than a manual, remote control, without cables, to manage its operation.
