Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ESP32-WROOM-32E and ESP32-WROOM-32UE are two general-purpose Wi-Fi + Bluetooth + Bluetooth LE MCU modules that are powerful and versatile enough to be used in low-power sensor networks and for demanding tasks such as voice encoding, audio streaming and MP3 decoding.

The ESP32-WROOM-32E uses a PCB on-board antenna and the ESP32-WROOM-32UE uses a connector to connect an external antenna.
