.. zephyr:board:: rpi_pico2
Overview
********
The Raspberry Pi Pico 2 is the second-generation product in the Raspberry Pi
Pico family. From the `Raspberry Pi website <https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html>`_ is referred to as Pico 2.
There are many limitations of the board currently. Including but not limited to:
- The Zephyr build only supports configuring the RP2350A with the Cortex-M33 cores.
- As with the Pico 1, there's no support for running any code on the second core.
Hardware
********
- Dual Cortex-M33 or Hazard3 processors at up to 150MHz
- 520KB of SRAM, and 4MB of on-board flash memory
- USB 1.1 with device and host support
- Low-power sleep and dormant modes
- Drag-and-drop programming using mass storage over USB
- 26 multi-function GPIO pins including 3 that can be used for ADC
- 2 SPI, 2 I2C, 2 UART, 3 12-bit 500ksps Analogue to Digital - Converter (ADC), 24 controllable PWM channels
- 2 Timer with 4 alarms, 1 AON Timer
- Temperature sensor
- 3 Programmable IO (PIO) blocks, 12 state machines total for custom peripheral support
- Flexible, user-programmable high-speed IO
- Can emulate interfaces such as SD Card and VGA
Supported Features
==================

Connections and IOs
===================
The default pin mapping is unchanged from the Pico 1 (see :ref:`rpi_pico_pin_mapping`).
Programming and Debugging
*************************
.. zephyr:board-supported-runners::
The overall explanation regarding flashing and debugging is the same as for :zephyr:board:`rpi_pico`.
See :ref:`rpi_pico_programming_and_debugging` in :zephyr:board:`rpi_pico` documentation. N.b. OpenOCD support requires using Raspberry Pi's forked version of OpenOCD.
Below is an example of building and flashing the :zephyr:code-sample:`blinky` application.
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: rpi_pico2/rp2350a/m33
:goals: build flash
:flash-args: --openocd /usr/local/bin/openocd
