Raspberry Pi Pico Microcontroller Boards

• Overview: The Raspberry Pi Pico is a series of development boards powered by RP2040 or RP2350 microcontrollers. They are programmed via MicroPython, C, or C++ by flashing binaries to on-board flash memory. They do not run Linux.
• Generations:
  • First Generation (RP2040): Includes Pico, Pico H, Pico W, and Pico WH.
  • Second Generation (RP2350): Includes Pico 2, Pico 2 with headers, Pico 2 W, and Pico 2 W with headers.
• Variant Naming Conventions:
  • W: Indicates wireless connectivity (Wi-Fi and Bluetooth).
  • H / "with headers": Indicates the board comes with presoldered pin headers (otherwise, they are castellated modules).
• Key RP2040 Features:
  • Dual-core M0+ processor (up to 133 MHz).
  • 264 kB SRAM and 2 MB on-board flash.
  • 8 Programmable I/O (PIO) state machines.
• Key RP2350 Features:
  • Choice of dual-core Arm Cortex-M33 or dual-core Hazard3 RISC-V processors (up to 150 MHz).
  • 520 kB SRAM and 4 MB on-board flash.
  • 12 Programmable I/O (PIO) state machines.
• Shared Features across all models:
  • 26 multi-function GPIO pins.
  • USB 1.1 controller (device and host support).
  • Drag-and-drop programming via USB mass storage.
  • Peripheral interfaces: 2x SPI, 2x I2C, 2x UART, 3x 12-bit ADC, 16x PWM channels.
  • Temperature sensor, low-power modes, and accurate timers.
• Wireless Capabilities (W models):
  • Wi-Fi: 802.11n (2.4 GHz), WPA3 security, and Soft access point support.
  • Bluetooth: 5.2 (supports BLE and Bluetooth Classic).
• Design Resources: Raspberry Pi provides open-access design files (Cadence Allegro), 3D STEP files, and Fritzing parts for hardware reproduction and enclosure design.
