Engineering inferenceProgrammable I/O state machines bit-bang protocols (WS2812, DVI, extra UARTs) without CPU load.
Engineering inferenceUSB is on the main chip (RP2350A), so the board can enumerate as a keyboard, MIDI device or CDC serial port.
Engineering inferenceThe board is the parent product. Each chip has its own memory, pins, capabilities and thermal limits.

b3bc9657-943d-5c3c-826c-90dcc8a3ffc1--wifiThe Raspberry Pi Pico 2 W is built around the RP2350A, alongside W25Q16JV, ABM8-272-T3, RT6154AGQW, CYW43439.
26 GPIO pins are exposed. Xirkit documents 49 board pins, 31 of them with pin-level electrical limits.
23 pins are 5 V tolerant and 3 are not — check each pin in the pinout table before connecting 5 V signals.
Documented output-high current per pin: ≤ 12 mA. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.
Supply range 1.8–5.5 V. Power inputs: VSYS (1.8–5.5 V), VBUS.
From $7 at Adafruit. Prices are observed unit prices before tax and shipping.
