SparkFun ESP32 Thing Developement Board WiFi & microcontroller Compatible with Bluetooth for IoT & prototyping Projects w/Integrated LiPo Battery Charger 4MB Flash Memory 3 to 3.6V Operating Range

The SparkFun ESP32 Thing is a comprehensive development platform the ESP32, their super-charged version of the popular ESP8266. Like the 8266, the ESP32 is a WiFi-compatible microcontroller, but to that it adds support for compatibility with BT, and nearly 30 I/O pins. And, thanks to the chip's pin multiplexing feature, those peripherals can be connected to just about any of the 28 broken out I/O pins. That means you decide which pins are RX, TX, MISO, MOSI, SCLK, SDA, SCL, etc. The ESP32s power and versatility will make it the foundation of IoT and connected projects for many years to come.
Why the name? We lovingly call it the Thing because its the perfect foundation for your Internet of Things project. The Thing does everything from turning on an LED to posting data with phant. io, and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the ESP32 Arduino Core.
The SparkFun ESP32 Thing equips the ESP32 with everything necessary to program, run and develop on the wonderchip. In addition to the WiFi/BLE SoC, the Thing includes an FTDI FT231x, which converts USB to serial, and allows your computer to program and communicate with the microcontroller. It also features a LiPo charger, so your ESP32 project can be battery-powered and truly wireless. Additionally, the board includes a handful of LEDs and buttons to aid in your development.
