Raspberry Pi Pico 2

Overview

The Raspberry Pi Pico 2 is the second-generation product in the Raspberry Pi Pico family. From the Raspberry Pi website 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

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 .
