Raspberry Pi Zero 2 W: New $15 board presents as much as 5x the efficiency of its predecessor


The Raspberry Pi Zero 2 W comes six years after the launch of the unique Pi Zero.

The most affordable member of the Raspberry Pi pc household now has a successor: the Raspberry Pi Zero 2 W , a 64-bit, quad-core follow-up to Zero W costing simply $15.

Launched right now by British computer-maker Raspberry Pi, the Pi Zero 2 W encompasses a 1GHZ CPU that the producer claims packs 5x the efficiency for multithread workloads than 2015's Raspberry Pi Zero.

The 65mm x 30mm board encompasses a quad-core 64-bit Arm Cortex-A53 CPU, clocked at 1GHz. At its coronary heart is a Raspberry Pi RP3A0 system-in-package (SiP), integrating a Broadcom BCM2710A1 SoC (the identical used within the Raspberry Pi 3, albeit clocked-down barely) with 512MB of LPDDR2 SDRAM. In addition to providing a big soar in multi-threading, Raspberry Pi says the upgraded processor within the Zero 2 W delivers a 40% efficiency enhance in single-thread executions.

The super-cheap and super-hackable Raspberry Pi Zero rapidly turned one in every of Raspberry Pi's best-selling units again when it launched six years in the past, because of its versatility and affordability worth – costing simply $5 at launch. 

It is also a agency favourite of Raspberry Pi co-founder, Eben Upton. "Of all of the merchandise we have launched, Zero remains to be the one I am proudest of: it most completely embodies our mission to present folks entry to instruments, and to get rid of value as a barrier," Upton wrote in a blog post saying the brand new machine.

"We have bought practically 4 million models of Zero, and its $10 wireless-enabled huge brother Zero W, and so they've made their means into all the things from good audio system to hospital ventilators." 

The Zero is not the most cost effective machine in Raspberry Pi's vary – this honor goes to the Raspberry Pi Pico, a microcontroller board constructed on Raspberry Pi's custom RP2040 silicon that was launched at first of 2021. On the different finish of the dimensions you've the likes of the Raspberry Pi 4 Model B and Raspberry Pi 400, that are designed as extra reasonably priced replacements to conventional desktop PCs. The corporate noticed a huge uplift in sales in 2020 because of the Covid pandemic and the following name for working and studying from residence, which made its extremely reasonably priced and consumer-friendly units much more interesting. 

Very similar to the 2018 Raspberry Pi Zero W, which added wi-fi connectivity (therefore the 'W') to the unique Zero board from 2015, the Pi Zero 2 presents each wi-fi and Bluetooth connectivity. This comes within the type of 2.4GHz 801.11b/g/n wi-fi LAN and Bluetooth 4.2. There's additionally help for Bluetooth Low Vitality (BLE).

When it comes to bodily connectivity, there is a MicroSD card clot, CSI-1 digital camera connector, USB on-the-go (OTG) port, and 40-pin GPIO header. Video output is by way of a mini-HDMI port. Because of the similarities in dimension and connectivity, the Zero 2 W can be utilized as a drop-in alternative for the unique Pi Zero and Zero W, which additionally means the brand new board suits inside most present Raspberry Pi Zero circumstances.

That stated, the discerning could discover some variations in heft: to compensate for the upper efficiency of the Zero 2 W, Raspberry Pi has needed to pack in additional heat-conducting copper to assist hold the machine cool whereas working. "For those who maintain a Zero W and a Zero 2 W in your fingers, you'll be able to actually really feel the distinction in weight," stated Upton.

To accompany Zero 2 W, Raspberry Pi has additionally launched a brand new official USB energy provide. It seems quite a bit like the unique energy provide unit for Raspberry Pi 4 PSU, however with a USB micro-B connector rather than the USB-C connector.

Raspberry Pi Zero 2 W specs embody:

  • Broadcom BCM2710A1, quad-core 64-bit SoC (Arm Cortex-A53 @ 1GHz)
  • 2.4GHz IEEE 802.11b/g/n wi-fi LAN, Bluetooth 4.2, BLE
  • 1 × USB 2.0 interface with OTG
  • HAT-compatible 40 pin I/O header footprint
  • MicroSD card slot
  • Mini HDMI port
  • Composite video and reset pin solder factors
  • CSI-2 digital camera connector
  • H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30)
  • OpenGL ES 1.1, 2.0 graphics
