ESP32 WIFI Bluetooth module with multiple communication interfaces

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
ESP32 WIFI Bluetooth module designed for integration into electronic projects and development solutions. The module combines WIFI and Bluetooth and provides 22 general purpose IO connections. It supports several communication and control interfaces including UART SPI SDIO I2C PWM I2S IR GPIO ADC and DAC.

The module includes 32 Mbit SPI Flash as standard and uses a 40 MHz crystal for the system clock. For wireless communication it provides both an onboard PCB antenna and an IPEX connection for an external antenna.

The ESP32 module is suitable for IoT applications wireless sensors control systems data acquisition home automation robotics and other projects where WIFI and Bluetooth connectivity are required. It can also be used with sensors displays motor controllers and other electronic modules.

IR is supported by the ESP32 chip but this does not mean that the module has a physical IR receiver or IR sensor mounted. IR signaling can be used through GPIO together with external IR components.

The module operates from 2.7 V to 3.6 V with 3.3 V recommended. The average working current is specified as approximately 80 mA while the power supply should be capable of providing at least 500 mA for stable operation.
