+
+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
+==================
+
+The ``rpi_pico2/rp2350a/m33`` board target supports the following
+hardware features:
+
+.. list-table::
+   :header-rows: 1

+
+Connections and IOs
+===================
+
+The default pin mapping is unchanged from the Pico 1 (see :ref:`rpi_pico_pin_mapping`).
+
+Programming and Debugging
+*************************
+
+As with the Pico 1, the SWD interface can be used to program and debug the
+device, e.g. using OpenOCD with the `Raspberry Pi Debug Probe <https://www.raspberrypi.com/documentation/microcontrollers/debug-probe.html>`_ .
