In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. It's our lowest-cost arduino-IDE programmable board! Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Additionally, the board includes a handful of LEDs and buttons to aid in your development.Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. It also features a LiPo charger, so your ESP32 project can be battery-powered and truly wireless. 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. The SparkFun ESP32 Thing equips the ESP32 with everything necessary to program, run and develop on the wonderchip. You can even program the Thing through the Arduino IDE by installing the ESP32 Arduino Core. The Thing does everything from turning on an LED to posting data with phant.io and can be programmed just like any microcontroller. Why the name? We lovingly call it the “Thing” because it’s the perfect foundation for your Internet of Things project.

The ESP32’s power and versatility will make it the foundation of IoT and connected projects for many years to come. Like the 8266, the ESP32 is a WiFi-compatible microcontroller, but to that, it adds support for Bluetooth low-energy (i.e BLE, BT4.0, Bluetooth Smart), and nearly 30 I/O pins.
