Raspberry Pi Zero W Adds Built In Wireless Radios

The Raspberry Pi Foundation recently introduced a $10 Pi Zero W which resembles the $5 single board Pi Zero computer it launched in 2015 but adds built in Wi-Fi and Bluetooth radios.

At the heart of the Raspberry Pi Zero W is a 1GHz single core Broadcom BCM2835 application processor and 512MB of RAM. Storage is handled by s micro SD card slot. The tiny board includes the following I/O options:

  • 1 x Mini HDMI
  • 1 x Micro USB OTG
  • 1 x Micro USB for power
  • 1 x 40-pin HAT compatible header
  • 1 x CSI camera connector
  • 1 x Composite video header
  • 1 x reset header

The Pi Zero W uses the same Cypress CYW43438 chip as the Pi 3 Model B and offers 802.11n Wi-Fi and Bluetooth 4.0. According to the Raspberry Pi Foundation, they found that many users were using USB wireless dongles along with a HID (keyboard/mouse) and they needed to carry around a hub or integrate it into their project. Adding built in wireless frees up the single Micro USB port for ither devices and hopefully allows smaller devices that use a Pi Zero as its brains.

Per RasPi.TV’s testing, the new Pi Zero W uses approximately 20mA more power than the Pi Zero which the site attributes to the wireless radios. While it more power than the previous model it is still half that of the Raspberry Pi 3 B. Specifically, the Pi Zero W pulls 120mA at idle and up to 170mA when playing back a 1080p video. Recording 1080p video from a camera uses ~230 mA. The SBC is rated at 0.6W to 1.2W (120 to 230 mA at 5.19V).

A modular official case is being released alongside the new board. US residents will be able to pick up the $10 single board computer at Adafruit, CanaKit, and Micro Center.

The Pi Zero has been used in a large variety of projects including robotics, arcade games, home automation and motion sensing cameras IoT, information displays, and electric skateboards. Integrating the wireless radio should make similar projects just a bit easier to out together.

Need a hand picking a low power ARM system?

If you are curious how the various ARM powered boards currently on the market compare to each other then the gang over at Phoronix has a real treat for you.  They have assembled a plethora of systems including the ODROID C1+, Raspberry Pi Zero, Raspberry Pi 2, Orange Pi Plus, Orange Pi PC, Banana Pi M2 as well as the Jetson TK1, and Jetson TX1 for comparison purposes.  Most of the systems use a Cortex A7 though you will also see an A5 as well as an A57.  The tests are varied as it can be difficult to determine what performance should be benchmarked on these systems although some like the OpenSSL test are obvious.  Since part of the reason you would choose a low power ARM system is the price, they wrap up with a performance-per-dollar rating to help you choose the best valued system for what you need it to do.

"For those interested in small, low-power ARM single-board computers, up for your viewing pleasure today are benchmarks of several different boards from the Raspberry Pi Zero to the Banana Pi M2."

Is the Pi Zero powerful enough for your project?

It can't play Crysis but if you want to know if the new Raspberry Pi Zero has what it takes to power your latest projects then look no further than this article at Phoronix in which they benchmark the new low cost SoC.  The $5 Zero is powered by a 1GHz single-core ARM processor with 512MB of RAM and a Broadcom BCM2708, outputs include mini HDMI and USB OTG ports, and a 40-pin header which you are going to be populating if you want networking.  As you would expect the Zero does sit at the bottom of the benchmark tables, however at this price point you are shopping for "just good enough", not top of the pack performance.  Check it out here.

Raspberry Pi Zero Released for $5

The Raspberry Pi Zero is a new version that lowers the cost of gigahertz-class computing devices to just $5. It is based on a 1.0 GHz ARM11 core from Broadcom that is about 40% faster than the original Raspberry Pi. It also has 512MB of RAM, which is a lot for embedded or hobbyist applications. In fact, it doubles the original Raspberry Pi Model A (and is on part with the Model B). Storage is handled by a microSD card slot, as is the case with every previous Raspberry Pi except the Compute Module.

They also offer an alternative to the $5 price tag. If you pick up the print edition of MagPi magazine #40, which is the Christmas 2015 issue, you will receive a free Raspberry Pi Zero. The Raspberry Pi Foundation says that they printed 10,000 copies of this magazine. This is probably much more interesting than a CD-ROM demo of Battlezone II.

Due to high demand, I'm not sure when you can expect to get one though.
