DIYables DIYables STEM V4 IoT Advanced Starter Kit, Arduino Uno R4 WiFi Compatible
Click to zoom
Quick Overview
The DIYables STEM V4 IoT Starter Kit is built around the DIYables STEM V4 IoT board, a development board fully compatible with Arduino Uno R4 WiFi. It combines an RA4M1 32-bit ARM Cortex-M4 microcontroller with an ESP32-S3 coprocessor for WiFi and Bluetooth, and programs in Arduino IDE using the Arduino Uno R4 WiFi board setting, libraries, and Uno shields.
The kit pairs the board with a Proto Screw Shield V1.0 expansion board, half-size breadboard, three types of jumper wires, a USB Type-C cable, and DC power jacks. Inputs and sensors include an RC522 RFID reader with tags, HC-SR04 ultrasonic sensor, HC-SR501 PIR motion sensor, DS18B20 temperature sensor, LDR light sensor module, potentiometer, button module, and 3x4 keypad. Outputs include a 1602 LCD display with blue backlight, SG90 servo motor, 28BYJ-48 stepper motor with ULN2003 driver, 5V 1-channel relay, LED modules, and an active piezo buzzer.
Ideal for beginners, students, teachers, and homeschoolers. With online tutorials provided, it covers everything from blinking LEDs and reading buttons to RFID door locks, motion alarms, smart home automation, and WiFi IoT dashboards.
