Raspberry Pi Zero 2 W
Raspberry Pi Zero: $5. Raspberry Pi Zero W: $10. Raspberry Pi Zero 2 W: Priceless. Nah, just kidding. It's $15.
Long committed to giving programmers affordable access to computer tech, Raspberry Pi's latest release, the Zero 2 W, appears to indicate the organization is also committed to helping them learn their 5 Times Table. The original Raspberry Pi Zero came out around 6 years ago for an incredibly cheap 5 bucks. And even at 3 times that amount, I would call the latest iteration "incredibly cheap" too. In fact, if Raspberry Pi runs through the entire 5 Times Table I learned in elementary school, which stopped at 5 x 10, they would still be selling some of the lowest cost, highest quality boards for their power and, as demonstrated nicely by the Zero 2 W, size.
The highlight of the Zero 2 W is that Raspberry Pi has upgraded it with the processor from the Raspberry Pi 3, without increasing its size, which remains the same as the original Zero. Raspberry Pi founder, Eben Upton, reports, "Raspberry Pi Zero 2 W uses the same Broadcom BCM2710A1 SoC die as the launch version of Raspberry Pi 3, with Arm cores slightly down-clocked to 1GHz, bundled into a single space-saving package alongside 512MB of LPDDR2 SDRAM. The exact performance uplift over Zero varies across workloads, but for multi-threaded sysbench it is almost exactly five times faster."
Additionally, nearly all Raspberry Pi Zero cases and accessories should be compatible with the Zero 2 W.
