Pimoroni Pico Plus2

Overview

The Pimoroni Pico Plus 2 [1] is a compact and versatile board featuring the Raspberry Pi RP2350B SoC. It includes USB Type-C, Qwiic/STEMMA QT connectors, SP/CE connectors, a debug connector, a reset button, and a BOOT button.

Hardware

  • Dual Cortex-M33 or Hazard3 processors at up to 150MHz

  • 520KB of SRAM, and 4MB of on-board flash memory

  • 16MB of on-board QSPI flash (supports XiP)

  • 8MB of PSRAM

  • USB 1.1 with device and host support

  • Low-power sleep and dormant modes

  • Drag-and-drop programming using mass storage over USB

  • 48 multi-function GPIO pins including 8 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

  • USB-C connector for power, programming, and data transfer

  • Qwiic/STEMMA QT(Qw/ST) connector

  • SP/CE connector

  • 3-pin debug connector, this can use with Raspberry Pi Debug Probe [2].

  • Reset button and BOOT button (BOOT button also usable as a user switch)
