Description

Raspberry Pi Pico 2W

Raspberry Pi Pico 2W is the latest addition to the Pico 2 family, now featuring wireless capability! It is built on the second-generation microcontroller IC, the RP2350A, designed and produced by the Raspberry Pi engineering team.

 

 

Enhanced Microcontroller Development Board

2nd generation of Raspberry Pi Pico W board comes with the following enhancements:

• CPU: Two Dual-Core CPU:
  • Dual ARM Cortex-M33 Cores
  • Dual RISC-V Hazard3 Cores
• System clock up to 150MHz
• SRAM: 520KByte
• 4MByte QSPI Flash Memory
• Comprehensive Security: ARM TrustZone, 8KB on-chip OTP Storage, Secure boot
• XIP v2 for better flash memory interface
• 12 PIO state machines (3 blocks)

We probably have lots of microcontrollers in our house already. For example, a washing machine is controlled by a microcontroller; most likely our watch is too; there is also one in a microwave. Of course, all these microcontrollers already have their application programs. This Raspberry Pi Pico 2W is a microcontroller board that can perform physical computing and can be easily reprogrammed over a USB connection.

A More Powerful MCU Dev Board (Dual-Core ARM Cortex-M33)

Raspberry Pi Pico W comes with dual ARM Cortex-M0+, while the new Pico 2W comes with a Dual-Core ARM Cortex-M33 and a Dual-Core RISC-V Hazard3. Flexible clocking system, with configurable up to a maximum speed of 150MHz! This tiny MCU comes with a whopping 520 Kbyte of SRAM, an external QSPI Flash with a capacity of 4 MByte, and enhanced eXecute In Place (XIP v2). Larger RAM and Flash size enable you to write high-level programming languages like MicroPython and CircuitPython for Raspberry Pi Pico 2W.

 

 

New Pico 2 Series with Wireless by Raspberry Pi

 

Compact and Ready to be Mounted into the Product

 

Raspberry Pi Pico 2W preserves the good of its presuccesor, it is ready to be embedded in any product out of the box. If you choose the version without pre-soldered headers, it is ready for SMT (Surface Mount Technology). Raspberry Pi Pico 2W is extended out to a 40-pin 21×51 DIP (Dual Inline Package) style, 1mm thick PCB with 0.1″ (100mil) through-hole pins. The pins are further extended to the PCB edge with a castellated circuit board. This enables it to be soldered to another PCB board without the need for extra header pins, making it a smaller and more compact finished product. Awesome!
