在下曾經使用 ESP32-S3 0.42in OLED 來製作模仿 O.MG 的 USB HID 裝置來無線控制宿主系統(主要是電腦)
但 ESP32-S3 0.42in OLED 與大多數 微控制器開發板 相同，都是使用 USB插口，即是需要使用 USB線 才能連接
在下希望能找到一款不需要額外工具便能夠直接安裝到 USB插口 的 微控制器開發板 來達到效果
外觀
結果確實找到其中一款使用 USB Type-A 插頭的 微控制器開發板
而且同樣是 ESP32系列 的 ESP32-S2
查閱資料後，發現 ESP32-S2 同樣支援 USB HID ，因此可以製作類似
使用 ESP32-S2-WROOM 的開發板 的正面
ESP32-S2-WROOM 的晶片在金屬殼下保護著，不過引腳則引出到外殼外
但引腳間距並非 0.1寸 或 2.54毫米 ，因此不能使用一般引腳座
板載LED ，與 IO17 連接，高電壓時亮著
按壓按鈕，與 IO0 連接，按下時接地，按下時通電可載入至 起動模式
天線焊接位，能焊接 IPEX天線，但預設是沒有焊接
ESP32-S2-WROOM 開發板 的背面
ESP32-S2-WROOM 的背面標示前方向引腳的名稱
雖然 ESP32-S2-WROOM 有標示引腳，但引腳的距離很少，要安全地引出引腳使用並不容易
使用 USB Type-A 插頭，方便連接到電腦

總結
由於 ESP32-S2 直接使用 USB Type-A 插頭，而且支援 WiFi 及 USB HID 功能，因此在下覺得更方便連接到電腦
在下亦將之前的 Sketch 修改，只是美中不足的是必須使用 序列輸出 來查看 IP
當連接到 ESP32* 的 WiFi 存取點 (Access Point) 後
在沒有修改 ESP32* 的 網絡設定的情況下， 預設閘道 (Default Gateway) 的 IP 必定是 192.168.4.1
但如果讓 ESP32-S2-WROOM 連接到其他 WiFi網絡 後，便需要在 序列輸出 才能查看 IP
然而，被連接的 宿主系統 未必有查看 ESP32-S2-WROOM 序列輸出 的軟件，連接的 WiFi網絡 亦未必有存取權查看 已連接網絡的裝置的 IP
因此可以使用 ESPmDNS.h 來設定 ESP32* 的 主機名稱 (Hostname) ，便可以直接以 主機名稱 來連接到 ESP32-S2-WROOM 而不需要獲知 IP
基本上這個專案只是使用 ESP32-S2-WROOM 來代替 ESP32-S3 0.42in OLED 的更新版
效果其實是完全相同，只是加強了方便使用的網頁操作界面
