SparkFun原廠 IoT RedBoard - RP2350 開發板 (WRL-27708)
Product Overview 產品概述
The SparkFun RP2350 IoT RedBoard combines the Raspberry Pi® RP2350 microcontroller with the Raspberry Pi® RM2 radio module to provide a powerful and versatile wireless development platform in the Arduino R4 form factor. This IoT RedBoard also includes integrated battery power and charging circuits, µSD card slot, Qwiic connector, 3-pin debug header, as well as a 22-pin ribbon cable connector tied to the RP2350's HSTX (high-speed transmit) pins. The board shares a pinout between female headers and matching 0.1"-spaced plated through-hole (PTH) headers to allow you to choose between temporary or soldered connections.
SparkFun RP2350 IoT RedBoard 將 Raspberry Pi® RP2350 微控制器與 Raspberry Pi® RM2 無線電模組結合，以 Arduino R4 外形尺寸提供強大且多功能的無線開發平台。這款 IoT RedBoard 還包括整合式電池電源和充電電路、µSD 卡插槽、Qwiic 連接器、3 針調試接頭，以及與 RP2350 的 HSTX（高速傳輸）引腳連接的 22 針帶狀電纜連接器。該板在母接頭和匹配的 0.1 英寸間距鍍通孔 (PTH) 接頭之間共享一個引腳排列，以便您可以在臨時連接或焊接連接之間進行選擇。
Raspberry Pi's RP2350 MCU provides a unique dual-core, dual-architecture configuration that allows users to select, in software, between a pair of Arm© Cortex-M33 cores, a pair of Hazard3 RISC-V cores, or one of each all running at up to 150 MHz! Now, this doesn't mean the RP2350 is a quad-core microcontroller. Instead, users can select which two processors to run on boot. You can run two processors of the same type or one of each. This IoT RedBoard uses the RP2350B microcontroller variant, which has 48 GPIO, eight analog inputs, two UARTs, two SPI and I2C controllers, and a USB 1.1 controller for host and device support.
Raspberry Pi 的 RP2350 MCU 提供了獨特的雙核心、雙架構配置，讓使用者可以在軟體中選擇一對 Arm© Cortex-M33 核心、一對 Hazard3 RISC-V 核心或每個核心中的一個，所有核心的運行速度高達 150 MHz！現在，這並不意味著 RP2350 是四核心微控制器。相反，使用者可以選擇在啟動時運行哪兩個處理器。您可以運行兩個相同類型的處理器或分別運行一個。此 IoT RedBoard 使用 RP2350B 微控制器變體，它具有 48 個 GPIO、8 個類比輸入、2 個 UART、2 個 SPI 和 I2C 控制器以及一個 USB 1.1 控制器，用於主機和裝置支援。
The Raspberry Pi Radio Module (RM2) operates over an SPI interface. Along with supporting both WiFi 4 and Bluetooth® 5.2, the RM2 supports both basic (1 Mbps) and enhanced (2 or 3 Mbps) data rates for standard Bluetooth as well as BLE (Low Energy).
Raspberry Pi 無線電模組 (RM2) 透過 SPI 介面運作。除了支援 WiFi 4 和藍牙® 5.2 之外，RM2 還支援標準藍牙和 BLE（低能耗）的基本（1 Mbps）和增強（2 或 3 Mbps）資料速率。
The board includes two built-in expanded memory options: 16MB of external Flash and 8MB PSRAM connected to the RP2350's QSPI interface. The IoT RedBoard - RP2350 has software support for C++/C using the Raspberry Pi Pico SDK, MicroPython, and Arduino so that users can opt for their preferred programming environment and language.
該板包括兩個內建擴充記憶體選項：16MB 外部快閃記憶體和連接到 RP2350 的 QSPI 介面的 8MB PSRAM。 IoT RedBoard - RP2350 使用 Raspberry Pi Pico SDK、MicroPython 和 Arduino 支援 C++/C 軟體，以便使用者可以選擇自己喜歡的程式設計環境和語言。
