Quick Overview
The DIYables STEM V4B IoT Starter Kit is an all-in-one electronics and coding kit built around the DIYables STEM V4B IoT board — a board that works like the Arduino UNO R4 WiFi, combining the RA4M1 microcontroller with an ESP32-S3 WiFi module and adding an on-board prototyping area with extra pin breakout for enhanced connectivity. The kit includes 21 item sets covering sensors, displays, actuators, and expansion hardware, giving beginners and students everything they need to start building real IoT and electronics projects immediately.
The kit includes popular sensors such as the HC-SR501 PIR motion sensor, HC-SR04 ultrasonic sensor, DS18B20 temperature sensor, light sensor module, potentiometer, and active piezo buzzer module. For output and interaction, it features an I2C LCD 16x2 blue-background display, SG90 servo motor, 4x4 matrix keypad, an RFID kit with RC522 reader and tags, plus 8 buttons with colored caps, 40 LEDs in four colors, and 80 resistors. The Proto Screw Terminal Expansion Board, half-size breadboard, male-to-female and male-to-male jumper wires, USB cable, and DC power jack complete the setup.
Ideal for STEM education, classroom projects, homeschooling, maker learning, IoT prototyping, and anyone starting their journey in embedded programming and electronics with Arduino UNO R4 WiFi. Free online tutorials are available — search "DIYables STEM V4B Kit".
