DESCRIPTION
The SparkFun MicroMod ESP32 Function Board adds additional wireless options to MicroMod Processor Boards that do not have that capability. This special function board acts as a coprocessor that takes advantage of Espressif's ESP32 WROOM to add WiFi and Bluetooth® to your applications.
SparkFun MicroMod ESP32 功能板為不具備該功能的 MicroMod 處理器板添加了額外的無線選項。這款特殊功能板可用作協處理器，利用樂鑫的ESP32 WROOM 為您的應用添加WiFi和藍牙®。
At the core of the ESP32 WROOM module is the ESP32-D0WD-V3 chip which is designed to be both scalable and adaptive. ESP32 WROOM module on this board features 16MB of flash memory, 520kB of internal SRAM, an integrated 802.11 b/g/n WiFi transceiver, and dual-mode Bluetooth capabilities. Utilizing our handy M.2 MicroMod connector, no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector, then secure them to the main board with screws. The ESP32 WROOM module can then be controlled using AT commands via the serial UART port.
ESP32 WROOM 模組的核心是 ESP32-D0WD-V3 晶片，該晶元具有可擴展性和自適應性。此主機板上的ESP32 WROOM 模組具有 16MB 快閃記憶體、520kB 內部 SRAM、集成的 802.11 b/g/n WiFi 收發器和雙模藍牙功能。利用我們方便的 M.2 MicroMod 連接器，無需焊接即可將其連接到您的系統。只需將處理器和功能板斜邊連接器上的鑰匙與 M.2 連接器上的相應鑰匙相匹配，然後用螺釘將它們固定在主機板上即可。然後，可以通過串行 UART 埠使用 AT 命令控制 ESP32 WROOM 模組。
The ESP32 Function Board comes pre-flashed with AT-command firmware and acts as a serial-to-WiFi gateway. Next to the module is a USB-C connector and CP2102 USB-to-serial converter. Whether you want to add AT commands of your own, or flash custom firmware on the ESP32, you can use this port to reprogram the ESP32.
ESP32 功能板預閃爍了 AT 命令韌體，可用作串行到WiFi閘道。模組旁邊是一個 USB-C 連接器和 CP2102 USB 轉串行轉換器。無論您是要添加自己的 AT 命令，還是在 ESP32 上刷新自定義韌體，都可以使用此埠對 ESP32 進行重新程式設計。
Note: A MicroMod Processor and Main Board are not included with this MicroMod WiFi Function Board. These boards will need to be purchased separately.
注意：MicroMod 處理器和主機板不包括在此 MicroMod WiFi 功能板中。這些電路板需要單獨購買。
MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors and function boards on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!
MicroMod是一個模組化介面生態系統，將微控制器「處理器板」連接到各種「載板」外設。MicroMod 標準採用 M.2 標準，旨在輕鬆更換處理器和功能板。將您所需的專案專用載板與您選擇的相容處理器配對！
