SparkFun IoT RedBoard - ESP32 Development Board

The SparkFun IoT RedBoard is an ESP32 Development Board that includes Espressif's ESP32 WROOM is a powerful WiFi and Bluetooth MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. The USB-to-serial is achieved with a USB-C connector with through hole anchoring and the ubiquitous CH340G requiring fewer driver installs.
