Raspberry Pi Pico 2 W, Arm or RISC-V, Wi-Fi and Bluetooth 5.2 review

A 21 × 51 mm microcontroller board with a choice of dual Arm Cortex-M33 or dual RISC-V Hazard3 cores at 150 MHz, 26 GPIO, twelve PIO state machines, Wi-Fi and Bluetooth 5.2.

By Jean-Benoit Buisson

The bottom line A compact, precisely specified board: cores, memory, pin counts, radios and dimensions are all published. Logic voltage and toolchain are left out of a listing that otherwise reads like a datasheet.

The Pico 2 W listing, bullet by bullet

Six bullets: dual Arm Cortex-M33 or dual RISC-V Hazard3 processors at 150 MHz; 520 KB of on-chip SRAM and 4 MB of on-board QSPI flash; 2.4 GHz 802.11n Wi-Fi and Bluetooth 5.2; two UARTs, two SPI and two I2C controllers, 24 PWM channels, a USB 1.1 controller and PHY with host and device support, and 12 PIO state machines; 26 multi-purpose GPIO, four of them usable as ADC; and 21 × 51 mm.

Two architectures on one Raspberry Pi board

Arm or RISC-V, chosen by the user. The first bullet names both core types. For most projects the choice is invisible; for anyone learning RISC-V, it is a low-cost way in.

PIO state machines

Twelve programmable I/O blocks can generate signals — LED protocols, custom serial links — without loading the main cores. It is the feature that distinguishes this board’s pin list from the others here.

A datasheet-style listing with two gaps

Six bullets of figures and none on logic voltage or programming environment. Both have to be looked up in Raspberry Pi’s own documentation.

Availability

At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 12 € to 14 €.

It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.

The American Amazon catalogue lists the product, yet no seller was offering it.

Every figure here is Keepa’s reading on the date this page was last updated. Stock and prices can change at any time.

Prices quoted in this text were read on 15 September 2026. The live price is at the top of the page.

Where it earns its place, and where it falls short

Strengths

A choice of Arm Cortex-M33 or RISC-V Hazard3 cores on the same chip
Twelve PIO state machines for custom hardware protocols
Wi-Fi and Bluetooth 5.2 on a 21 × 51 mm board

Compromises

No logic voltage or USB connector type given
No programming environment named
Only 4 of the 26 GPIO can be used as ADC inputs

Questions makers ask before buying

What does PIO mean on the Pico 2 W?

The fourth bullet lists 12 PIO state machines: programmable I/O blocks that run small programs to generate or read custom signals independently of the main cores.

Does the Pico 2 W have Bluetooth?

Yes. The third bullet lists 2.4 GHz 802.11n Wi-Fi and Bluetooth 5.2.
