2024新品 Raspberry Pi Pico 2 W 高性能微控制器板 RP2350A 開發板
Raspberry Pi Pico是基於Raspberry Pi RP2350微控制器芯片的微控制器板。它被設計為RP2350的低成本但靈活的開發平台
The Raspberry Pi Pico 2 series of microcontroller boards is built on RP2350: a high-performance, secure microcontroller. With a higher core clock speed, double the on-chip SRAM, double the on-board flash memory, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities than the previous version. The Raspberry Pi Pico 2 series delivers a significant performance and feature boost while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico family.／Raspberry Pi Pico 2 系列微控制器板基於 RP2350：一款高效能、安全的微控制器。與之前的版本相比，具有更高的核心時脈速度、雙倍的片上SRAM、雙倍的板載快閃記憶體、更強大的Arm 核心、可選的RISC-V 核心、新的安全功能以及升級的接口功能。 Raspberry Pi Pico 2 系列提供了顯著的效能和功能提升，同時保留了與 Raspberry Pi Pico 系列早期成員的硬體和軟體相容性。
The Pico 2 W adds wireless functionality with a 2.4GHz 802.11n wireless LAN and Bluetooth 5.2 wireless radio and on-board antenna. The radio holds modular compliance certification the United States.／Pico 2 W 透過 2.4GHz 802.11n 無線 LAN 和藍牙 5.2 無線電和板載天線增加了無線功能。該收音機擁有美國模組化合規性認證。
