 ## Qwiic Connector
 
 The Nano R4 board features an onboard Qwiic connector that provides a simple, tool-free solution for connecting I²C devices. The Qwiic ecosystem, developed by SparkFun Electronics, has become an industry standard for rapid prototyping with I²C devices, allowing you to connect sensors, displays, and other peripherals without soldering or complex wiring. This makes it perfect for quickly building sensor networks, adding displays, or expanding your project's capabilities with minimal effort.
