A Closer Look at SparkFun Espressif Boards
Wide Feature Range
SparkFun doesn't offer a single "one-size-fits-all" Espressif board. Instead, we cater to diverse needs and skill levels by providing a variety of options, each with its own unique set of features. From entry-level boards to advanced GNSS surveyors, an ESP module can be found in a multitude of SparkFun products!
Qwiic Ecosystem Integration
SparkFun's development boards boast seamless integration with the Qwiic ecosystem. This system uses I2C communication and a standardized 4-pin JST connector, allowing for effortless "plug-and-play" connection of various sensors and actuators from different manufacturers.
Open-Source Hardware
SparkFun's ESP development boards adhere to open-source principles. This means the schematics, hardware design files, and firmware are readily available for users to modify, customize, and contribute to. This transparency fosters community collaboration and empowers users to fully understand and optimize their hardware.
ESP32
The SparkFun ESP32 Thing is a comprehensive development platform for Espressif’s ESP32, their super-charged version of the popular ESP8266.
