Product Overview 產品概述
This SparkFun ESP32 IoT RedBoard version is an ESP32 Development Board specially programmed to run MicroPython out of the box. It makes it easy to get started using SparkFun's 40+ MicroPython-capable modules.
此 SparkFun ESP32 IoT RedBoard 版本是經過專門編程以開箱即用運行 MicroPython 的 ESP32 開發板。它讓您能夠輕鬆開始使用 SparkFun 的 40 多個支援 MicroPython 的模組。
The ESP32-D0WDQ6 chip, designed to be both scalable and adaptive, is at the core of this module. The IoT RedBoard can target various applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding. The IoT ReadBoard also utilizes our handy Qwiic Connect System, which means no soldering or shields are required to connect it to the rest of your system!
ESP32-D0WDQ6 晶片是該模組的核心，其設計兼具可擴展性和自適應性。 IoT RedBoard 可以針對各種應用，從低功耗感測器網路到最嚴苛的任務，例如語音編碼、音樂串流和 MP3 解碼。 IoT ReadBoard 還利用了我們便捷的 Qwiic Connect 系統，這意味著無需焊接或屏蔽即可將其連接到系統的其餘部分！
The USB-to-serial is achieved with a USB-C connector with through-hole anchoring, and the ubiquitous CH340G requiring fewer driver installs. We've included 3.3V voltage translation and a Qwiic connector to the board's edge to allow for quick and seamless connection to our ever-growing line of I2C-based Qwiic products. The board even includes a microSD socket if your application requires you to log and save data to a memory card. We have included a 2-pin JST connector for remote power to attach a single-cell LiPo battery. A built-in LiPo charge IC (MCP73831) and fuel gauge (MAX17048) also exist.
USB 轉串行是透過帶有通孔錨定的 USB-C 連接器實現的，並且無處不在的 CH340G 需要安裝更少的驅動程式。我們在電路板邊緣配備了 3.3V 電壓轉換和Qwiic 連接器，以便快速無縫地連接到我們不斷增長的基於 I2C 的Qwiic 產品系列。如果您的應用程式需要您記錄資料並將其保存到記憶卡，該板甚至還包含一個 microSD 插槽。我們已包含一個 2 針 JST 連接器，用於遠端電源連接單節 LiPo 電池。還存在內建 LiPo 充電 IC（MCP73831）和燃油計（MAX17048）。
The operating system is freeRTOS with LwIP, and TLS 1.2 with hardware acceleration is also built-in. Secure (encrypted) over-the-air (OTA) upgrades are also supported so that users can upgrade their products even after release at minimum cost and effort.
作業系統是LwIP的freeRTOS，也內建了有硬體加速的TLS 1.2。還支援安全（加密）無線（OTA）升級，以便用戶即使在發布後也可以以最低的成本和精力來升級他們的產品。
