ESP32 Wroom + UFL Connector

The ESP32-WROOM from Espressif Systems is a Wi-Fi+BT+BLE MCU module that supports variety of applications such as low-power sensor networks, voice encoding, music streaming and MP3 decoding. The module has an integrated 2.4 GHz Wi-Fi and Bluetooth chip. It supports a data rate of up to 150 Mbps and has a sleep current of under 5 micro ampere, making it suitable for battery powered and wearable electronics applications. The module has an embedded antenna switch, power amplifier, low-noise receive amplifier, filters, and power management modules. The module supports secure (encrypted) over the air (OTA) upgrades and is FCC/CE (RED)/IC/TELEC/KCC/SRRC/NCC and Wi-Fi Alliance certified.

What makes the ESP32-WROOM-32U from the rest of the WROOM series, is that it integrates a U.FL connector on the module.
