Arduino EK Wifi Starter Kit
The Arduino UNO EK R4 WiFi Starter Kit is a versatile beginner-friendly package crafted for electronics prototyping, IoT and embedded applications. At its core is the UNO EK R4 board, which combines a 32-bit Renesas R7FA4M1AB3CFM microcontroller with an ESP32-S3 module for Wi-Fi and Bluetooth connectivity, alongside a 12×8 programmable LED matrix.
It boasts 256 kB flash, 32 kB SRAM, 8 kB EEPROM, a 14-bit ADC, DAC channels and CAN bus interface. Code uploads in seconds over USB-C, while onboard regulators accept 6–24 V inputs.
The kit includes a 400-tie-point solderless breadboard, 220 ? resistor, active buzzer, DHT11 humidity/temperature sensor, male jumper wires and five 5 mm LEDs (red, green, blue, white and yellow).
These components let you build weather stations, alarm buzzers and interactive displays. Compatible with the Arduino IDE and C/C++ libraries, it’s ideal for students, makers and educators seeking hands-on learning and rapid prototyping. Explore systems, connect cloud services via Wi-Fi and bring electronic ideas to life with this toolkit.
Arduino EK Wifi Starter Kit Contains:
Original Arduino UNO EK R4 WiFi
The board merges a Renesas R7FA4M1AB3CFM (Cortex-M4F) MCU with an ESP32-S3 module for Wi-Fi and Bluetooth. It features a 12×8 RGB LED matrix, 256 kB flash memory, 32 kB SRAM, 8 kB EEPROM and standard digital/analog headers.
220-ohm Resistor
A ¼ W carbon-film resistor with 220 ? resistance and ±5% tolerance, perfect for limiting current to LEDs, sensors or buzzers. Axial leads fit snugly into solderless breadboards for quick circuit prototyping and testing.
Type-C USB Cable (1 m)
Durable 1 m USB-C to USB-A cable delivers 5 V/3 A power and high-speed data transfer. Nylon-braided jacket resists kinks and wear, ensuring reliable connection between your computer and Arduino board.
Active Buzzer Module (3.3–5 V)
Compact piezo buzzer with built-in driver, operating from 3.3 V to 5 V logic levels. Mountable PCB module includes transistor switch and resistor, enabling direct GPIO control for alarms, tones and notifications.
400-Tie-Point Solderless Breadboard
Reusable prototyping board offering 400 tie points in a 0.1? pitch layout with continuous power rails. No-solder design allows rapid insertion of ICs, resistors, LEDs and jumper wires for flexible circuit assembly.
DHT11 Humidity & Temperature Sensor Module
Digital sensor module measuring 20–90% RH humidity (±5% accuracy) and 0–50 °C temperature (±2 °C accuracy). Uses a single-wire communication protocol and includes pull-up resistor and header pins for breadboard use.
Male-to-Male Jumper Wires
Set of 20 Dupont cables, each 20 cm long with 0.1? pitch male connectors. Flexible silicone insulation rated for 300 V/3 A makes them ideal for reliable connections on breadboards, sensors and modules.
5 mm LEDs (Green, Red, Blue, White, Yellow)
Pack of five diffused-lens LEDs (5 mm diameter) with forward voltages of 2.0–3.3 V and 20 mA operating current. Long-lead anode and short-lead cathode simplify orientation in prototype circuits.
