Meet Raspberry Pi Pico W: The 'W' stands for Wi-Fi

Meet Raspberry Pi Pico W: The 'W' stands for Wi-Fi

Trending 2 months ago 31

The Raspberry Pi Pico, released backmost successful January 2021, was a tiny SBC (single committee computer) with an arsenic tiny $4 terms tag. Since then, astir 2 cardinal Pico boards person been sold.

Today sees the Pico getting a highly requested diagnostic -- Wi-Fi.

And the terms tag is inactive tiny, with the new Raspberry Pi Pico W coming successful astatine lone $6.

The RP2040 microcontroller is unchanged, and inactive features a 133MHz dual-core Arm Cortex-M0+ chip, 264KB of SRAM, and 2MB of QSPI flash storage.

And this each fits onto a committee measuring 21mm x 51mm. This means that if you person projects that usage the Pico, but could payment from Wi-Fi, the Pico W is simply a drop-in replacement.

But the eagle-eyed mightiness announcement a metallic square. 

This is the location for the Infineon CYW43439 spot that supports 2.4GHz 802.11b/g/n Wi-Fi.

That spot besides supports Bluetooth 5.2, but astatine motorboat lone Wi-Fi is supported.

The existent question is whether Wi-Fi is worthy the $2. The leap from $4 to $6 is rather a jump, but if you request wireless, it's worthy it for the on-board solution.

Also caller is simply a Pico with pre-soldered header pins, called the Pico H for $5. Coming successful August is simply a Pico WH, a Wi-Fi mentation with header pins, which volition acceptable you backmost $7.
