'The Raspberry Pi Zero series is the smallest version of the popular single-board computer that most people have experience with, but there's one Pi that's even smaller: the Raspberry Pi Pico. Launched in January of 2021 for just $4, the Pico's RP2040 microcontroller incorporates a pair of 133MHz Arm Cortex-M0+ CPU cores and 264 kilobytes (not megabytes) of memory. The low specs and low price make it well-suited for single-purpose devices that don't need much processing power instead of running general-purpose software like the larger Pi boards. To help support companies who want to use the Pico as a basis for Internet-connected smart devices, the Raspberry Pi Foundation is introducing a few new variants of the Pico today. The most notable, the Raspberry Pi Pico W, adds built-in Wi-Fi connectivity to the board while increasing the price from $4 to $6.' -- source: https://arstechnica.com/gadgets/2022/06/the-tiniest-raspberry-pi-gets-a-new-...
