Pinout

J1 (left header, physical pins 1-20) (20 pins)

Same physical pinout as Raspberry Pi Pico (official statement in the Raspberry Pi documentation repository, cross-checked against the Pico 2 pinout figure). Default UART/I2C/SPI pin assignments per the pico-sdk pico2.h board header are identical to pico.h. Type letters are an editorial summary; the datasheet itself does not publish a typed pin table. · Source: Raspberry Pi Pico 2 Datasheet (RP-008299-DS-3, Release 5) · RP-008299-DS-3-pico-2-datasheet.pdf#section-3-1-raspberry-pi-pico-2-pinout

J2 (right header, physical pins 21-40) (20 pins)

Same provenance as J1. GPIO0-22 are digital-only; GPIO26-28 work as digital GPIO or ADC inputs (software-selectable). The ADC-capable GPIO26-29 have an internal reverse diode to the 3V3 rail: input voltage must not exceed 3V3 plus about 300 mV, and driving them while the board is unpowered leaks current into the 3V3 rail (datasheet section 5.2). · Source: Raspberry Pi Pico 2 Datasheet (RP-008299-DS-3, Release 5) · RP-008299-DS-3-pico-2-datasheet.pdf#section-3-1-raspberry-pi-pico-2-pinout

The Raspberry Pi Pico 2 is the RP2350 successor to the Pico: same 40-pin castellated/through-hole format, same pinout, 4 MB of on-board flash (Winbond W25Q32RV), micro-USB with drag-and-drop UF2 flashing and 3-pin SWD pads. Raspberry Pi states hardware and software compatibility with Raspberry Pi Pico 1. This page renders the MCUID data record with every field tied to a fixed official source.

Common questions this site answers

Also known as: pico2, raspberry pi pico 2, rpi pico 2

No module layer

Like the Pico, this board has no module layer — the RP2350A (QFN-60 package) is soldered directly on the board. The compatible-modules list below is intentionally empty.

What changed from Pico 1 (official comparison)

The Pico 2 datasheet's "Differences from Raspberry Pi Pico" section lists the changes verbatim:

double the on-board flash (2 MB -> 4 MB)
RP2040 -> RP2350: 133 -> 150 MHz core clock, 264 -> 520 kB SRAM, dual Cortex-M0+ -> dual Cortex-M33, plus dual Hazard3 RISC-V cores, TrustZone, signed boot, 8 kB antifuse OTP, SHA-256 acceleration, hardware TRNG and glitch detectors
2 PIO blocks (8 state machines) -> 3 PIO blocks (12 state machines)

Everything mechanical and pin-level stays compatible: the pinout and board layout are officially the same as Pico and Pico H.

GPIOs used by internal board functions

Identical to Pico: GP25 user LED (single-color, not addressable RGB), GP24 VBUS sense, GP23 SMPS power-save, GP29 VSYS monitor (ADC3, VSYS/3) — and, as on Pico, none of the four is brought out on the J1/J2 header. See the claim table for the fixed source of each.

Flashing and debug

Hold BOOTSEL at power-up, then drag-and-drop a .uf2 onto the mass-storage drive; the USB boot code is in ROM. The 3-pin SWD pads (SWDIO, GND, SWCLK — no power pin) sit on the bottom edge like on the Pico.

ADC pins: the reverse-diode limit

GPIO0-22 are digital-only; GPIO26-28 are software-selectable digital GPIO or ADC inputs. As on Pico, the ADC-capable GPIO26-29 have an internal reverse diode to the 3V3 rail: input must stay below 3V3 + ~300 mV, and driving them while the board is unpowered leaks current into the 3V3 rail.

Default UART/I2C/SPI pins

The pico-sdk pico2.h board header (tag 2.3.1) defines the same software defaults as the original Pico: UART0 on GP0/GP1, I2C0 on GP4/GP5, SPI0 with RX GP16, CSn GP17, SCK GP18, TX GP19.
