Product description: SparkFun Thing Plus - ESP32 WROOM (U.FL) - module with WiFi and Bluetooth communication - SparkFun WRL-17381
The module produced by SparkFun and equipped with the ESP32 WROOM system, with the possibility of wireless WiFi and Bluetooth communication. SparkFun Thing Plus has a single-core 32-bit Xtensa LX6 processor with a clock speed of up to 240 MHz and a U.FL antenna connector. The board is also equipped with a Qwiic connector, based on the I2C interface. Thanks to it, it is possible to quickly and easily connect to another system without the need to solder the connectors. The module offers a lot of possibilities in the field of IoT systems and can be used both to control LEDs and to transfer data to a specific platform. Thing Plus can also be programmed using the Arduino IDE.
The product is compatible with Arduino!
The manufacturer has prepared a detailed user guide that significantly facilitates working with the module.
