It is a microcontroller with built-in WiFi and Bluetooth module. You can choose to use IoT (Internet Of Things) technology in your projects to provide maximum comfort to both the constructor and the user. This small card, which is in the structure of NodeMCU, contains chips that provide high-speed and low-power Wi-Fi and Bluetooth connections internally.
Unlike other models of the same series, “Ipex Antenna” type is used in ESP32-WROVER-IB. This “Ipex” antenna technology offers more coverage than the models with PCB antennas. You can use this type of antenna in your projects where you need shorter distance communication. This card uses 2.4GHz Wi-Fi technology and “Dual Mode Bluetooth” (Classic and low energy) technology together. Thanks to this feature, it provides unmatched connection performance in certain applications.
