Product description: SparkFun Thing Plus - ESP32 WROOM - with WiFi and Bluetooth communication - USB-C - SparkFun WRL-20168
The SparkFun Thing Plus - ESP32 WROOM module is a Feather -sized board that supports wireless WiFi and Bluetooth communication . It has a built-in ESP32-D0WDQ6 chip , which provides the user with up to 21 multi-functional GPIO pins . Among them we find, among others, 13x 12-bit ADC channels, 2x DAC channels, 16x PWM, 8x pins for touch sensors and 3x SPI. There is also a Qwiic connector on the board, thanks to which it is possible to quickly and easily connect to another system without the need to solder the connectors. The SparkFun Thing Plus module offers a wide range of possibilities in the field of IoT systems and can be used both to control LEDs and to transfer data to a specific platform.
