SparkFun IoT RedBoard - ESP32 Development Board 開發板 (WRL-19177)
DESCRIPTION
The SparkFun IoT RedBoard is an ESP32 Development Board that includes everything but the kitchen sink! Espressif's ESP32 WROOM is a powerful WiFi and Bluetooth® MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. The IoT RedBoard can target a wide variety of 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!
SparkFun 物聯網紅板是一款 ESP32 開發板，包括除廚房水槽之外的所有功能！樂鑫 ESP32 WROOM 是一款功能強大的WiFi和藍牙 ® MCU 模組，適用於各種應用。該模組的核心是 ESP32-D0WDQ6 晶片，該晶元具有可擴展性和自適應性。物聯網紅板可以針對各種應用，從低功耗感測器網路到最苛刻的任務，如語音編碼、音樂流和MP3解碼。物聯網讀板還利用了我們方便的Qwiic連接系統，這意味著無需焊接或遮罩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 edge of the board 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.
USB轉串行是通過具有通孔錨固的USB-C連接器和無處不在的CH340G實現的，需要安裝更少的驅動程式。我們在電路板邊緣包括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I系列。2基於C的Qwiic產品。該板甚至包括一個microSD插座，如果您的應用需要您記錄數據並將其保存到存儲卡。
The operating system is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that users can upgrade their products even after their release, at minimum cost and effort.
操作系統是帶有LwIP的freeRTOS;還內置了具有硬體加速功能的TLS 1.2。還支援安全（加密）無線（OTA）升級，以便使用者即使在發佈后也可以以最低的成本和精力升級其產品。
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
SparkFun Qwiic Connect System是I的生態系統2C 型感測器、執行器、遮罩和電纜，使原型設計更快，更不容易出錯。所有支援 Qwiic 的電路板均使用通用的 1mm 間距 4 針 JST 連接器。這減少了所需的PCB空間，並且極化連接意味著您不能將其錯誤地連接。
