Description
Its ESP32-WROOM-32U Chip Module with 3dBi Antenna, It has an integrated micro antenna connector on the chip module which is used to connect antenna with this connector. Antenna is basically a device which is used to convert the analog or digital signal in to the electromagnetic signal which is used for the wireless communications or connectivity.
ESP32-WROOM-32U: The ESP32-WROOM-32U is a highly integrated Wi-Fi and Bluetooth module based on the ESP32 microcontroller chip. It is part of the ESP32 series of modules developed by Espressif Systems. The module is based on the ESP32 microcontroller, which combines a dual-core processor, Wi-Fi (802.11 b/g/n), and Bluetooth functionality in a single chip. The dual-core architecture allows for efficient multitasking and better performance. The module supports Wi-Fi connectivity, allowing devices to connect to wireless networks and communicate over the Internet. It supports the standard Wi-Fi protocols, including 2.4 GHz Wi-Fi 4 (802.11 b/g/n). The module provides a number of General Purpose Input/Output (GPIO) pins, allowing for interfacing with various sensors, actuators, and external components. These pins can be used for digital input/output, analog input, PWM (Pulse Width Modulation), and other purposes. The ESP32-WROOM-32U is widely used in various IoT (Internet of Things) applications, smart home devices, industrial automation, wearable devices, and other projects that require wireless connectivity and processing capabilities. Its compact size, low power consumption, and extensive features make it a popular choice for developers and hobbyists in the embedded systems and IoT domains.
Antenna Details: Long-range 2.4G 3dBi Wifi Omni Directional Antenna with IPEX U.FL to SMA Male to Female Connector. Antenna with adjustable angle and integrated SMA connector of high quality. Designed for low-power 2.4GHz transceivers with appropriate connectors, such as 802.11b/g, Bluetooth, and other 2.4GHz telemetry modules. The antenna angle can be set to a 90° straight angle. If you are looking for extended WiFi range from your ESP8266, CC3000 or other WiFi based projects then this Antenna package is what you need. If you have a U.FL connector then use the cable, else the next most popular is the full size SMA connector in which case the 3DBI Antenna will screw on directly.
