KES 1,500

Microcontrollers

ESP32 DevKit V1 (WiFi + Bluetooth)

Dual-core ESP32 with built-in WiFi and Bluetooth. The go-to board for IoT projects, web dashboards and wireless sensor nodes.

KES 1,300

Microcontrollers

ESP8266 NodeMCU V3

Low-cost WiFi microcontroller. Great for simple IoT projects, RFID attendance systems and home automation.

KES 850

Microcontrollers

Arduino Nano (CH340)

Small Arduino board that fits on a breadboard. Same ATmega328P as the Uno, good for compact builds.

KES 950

Microcontrollers

Arduino Mega 2560

54 digital pins and 4 hardware serial ports. For projects with many sensors, displays or relays.

KES 2,800

MOSFETs & Transistors

IRFZ44N N-Channel Power MOSFET

55V, 49A power MOSFET in a TO-220 package. Standard gate drive, so it needs about 10V on the gate for full turn-on.

KES 120

MOSFETs & Transistors

IRLZ44N Logic-Level MOSFET

Logic-level N-channel MOSFET that switches fully from 5V Arduino pins. Use it for motors, LED strips and pumps.

KES 150

MOSFETs & Transistors

IRF540N N-Channel MOSFET

100V, 33A MOSFET in a TO-220 package for motor control, inverters and DC-DC converters.

KES 130

MOSFETs & Transistors

BC547 NPN Transistor (pack of 10)

General-purpose NPN transistors for switching small loads, LED drivers and sensing circuits.

KES 100

Sensors

DHT22 Temperature & Humidity Sensor

Digital temperature and humidity sensor, more accurate than the DHT11. Works with Arduino and ESP32.

KES 650

Sensors

HC-SR04 Ultrasonic Distance Sensor

Measures distance from 2 cm to about 4 m. Used in water level monitors, parking sensors and robots.

KES 300

Sensors

MFRC522 RFID Module + Cards

13.56 MHz RFID reader with a card and key tag. Build attendance systems and access control.

KES 550

Motors & Drivers

SG90 Micro Servo Motor

Small 180° servo for robot arms, door latches and pan-tilt mounts.
