Arduino Uno R4 WiFi Starter Kit
Overview
The Arduino Uno R4 WiFi Starter Kit (K000007_R4) is a comprehensive prototyping package based on the Renesas RA4M1 microcontroller. This kit combines the classic Uno form factor with modern enhancements, including an integrated ESP32-S3 module for 2.4GHz Wi-Fi and Bluetooth 5.0 connectivity. It features a 12x8 LED matrix for visual feedback and a Qwiic connector for rapid I2C prototyping without soldering.
Why Choose This Part
The board maintains the 5V logic compatibility of the original Uno while upgrading the processor to a 48MHz 32-bit Cortex-M4 with a built-in HID-capable USB-C port. It offers expanded memory with 256KB Flash and 32KB RAM, plus an onboard 12x8 LED matrix for debugging and user interface elements without external components.
Applications
Key Specifications
Getting Started
Engineers can begin development by installing the Arduino IDE and selecting the Arduino Uno R4 WiFi board package. The board is powered via USB-C or a DC jack (6-24V) and supports the standard Arduino library ecosystem for immediate peripheral integration. For advanced debugging, use the built-in HID support to emulate keyboards or mice.
