This board comes with an onboard ESP32 WROOM-32 WiFi, Bluetooth Classic, BLE Module, and a CAN Bus port with a transceiver. Also, onboard is an RGB LED, IO pins on a 0.1" pad.
Programming is accomplished through the popular Arduino IDE connected to the USB-to-Serial converter with USB-C connector, automatic bootloader and reset.
The ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.

Internet of Things Projects with ESP32: Build exciting and powerful IoT projects
The ESP32, a low-cost MCU with integrated Wi-Fi and BLE capabilities, comes with a variety of modules and development boards for building IoT applications efficiently. Wi-Fi and BLE are standard network stacks for Internet-of-Things applications providing cost-effective solutions for your business and project requirements.
This book is a fundamental guide for developing ESP32 programs and starts by explaining GPIO (General Purpose I/O) programming with sensor devices. The reader gets up to speed with ESP32 development through several IoT projects such as weather stations, sensor loggers, smart homes, Wi-Fi cams, and Wi-Fi wardriving. The reader learns how to use ESP32 boards to facilitate interactions between mobile applications and cloud servers, such as AWS.
By the end of this book, you'll have learned how to control a range of IoT projects using the ESP32 chip.
