Arduino

The UNO R4 board, a course in a box, and a sensor kit

Arduino’s board

The UNO R4 WiFi pairs a Renesas RA4M1 with an ESP32-S3 and adds CAN, Qwiic, a DAC and a 12 × 8 LED matrix. Its listing leaves logic voltage and memory to Arduino’s documentation.

Arduino kits

The Starter Kit R4 is a structured course: the UNO R4 WiFi, a printed book of 13 projects and more online. The Sensor Kit – Base promises over 10 sensors and tutorials without listing them one by one.

Arduino’s pattern

Official and well supported, thinly itemised. Neither kit gives a full parts list, and the sensor kit names no board as needed.
