The SparkFun Arduino UNO R4 WiFi Qwiic Kit is a great way to start with Arduino and the Qwiic-connect system. This kit includes everything you need to build a WiFi-enabled project, including an Arduino UNO R4 board, an assortment of Qwiic-enabled sensors and input boards, a Qwiic OLED Display, and a variety of other components to get you connected. Hooking up a handful of inputs and outputs to an Arduino UNO R4 has never been so easy.
The UNO universe expands with the Arduino UNO R4 WiFi: the same industry-standard form factor at 5V operating voltage, but with the enhanced performance of a RA4M1 32-bit microcontroller by Renesas with ESP32-S3-MINI coprocessor – for increased computational power, memory and speed – as well as WiFi® and Bluetooth® connectivity, a 12 x 8 LED matrix, and a Qwiic connector.
The SparkFun Arduino UNO R4 WiFi Qwiic Kit is a great way to learn about Arduino, WiFi, and electronics. With this kit, you can build your WiFi-enabled projects and connect your devices to the Internet of Things.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

There are a nice selection of peripherals to try out with little to no soldering, etc. Unfortunately most of the example programs listed on the Sparkfun site for the peripherals do not work with the Qwiic system and this Arduino. They need to be modified to use Wire1 instead of Wire for the I2c bus and their 'begin' statements need adjustment. However the forums are a big help to get things up and running.
