BC547 NPN Transistor
BC557 PNP Transistor
IRF520 MOSFET Driver Module (0-24V) | PWM Motor & LED Controller
-
Max Load: 24V DC / < 5A.
-
Control Voltage: 3.3V or 5V (PWM Compatible).
-
Output: Pulse Width Modulation (Speed/Dimming control).
-
Best For: LED Strips, Small DC Fans, and Solenoids.
IRLZ44N Logic Level MOSFET (N-Channel) | Arduino Compatible Transistor
Control high-power loads directly from your Arduino or ESP32. The IRLZ44N is a true logic-level MOSFET, meaning it fully turns on with 3.3 V or 5 V gate signals. Unlike the common IRFZ44N, it does not require a gate driver, making it ideal for simple and efficient microcontroller projects.
-
Type: Logic-Level N-Channel MOSFET
-
Maximum Voltage / Current: 55 V / 47 A
-
Gate (Control) Voltage: 5 V (fully compatible with Arduino and ESP32)
- Best for: PWM LED dimming, DC motor speed control, solenoids, relays, and other high-current loads.
LM358 Dual Op-Amp IC | Low Power Operational Amplifier (DIP-8)
The industry-standard chip for audio and signals. The LM358 contains two independent, high-gain operational amplifiers in a single 8-pin package. Unlike the older 741 Op-Amp, the LM358 is designed to work perfectly with a single power supply (like a battery).
-
Package: DIP-8 (Breadboard Friendly)
-
Supply Voltage: 3V to 32V
-
Best For: Pre-amplifiers, Active Filters, and Line Following Robots (Comparator).
NE555 Timer IC (NE555P, NE555N Precision Timer DIP-8)
-
Type: Precision Timer / Oscillator.
-
Package: DIP-8 (Fits standard breadboards).
-
Voltage: 4.5V - 16V DC.
-
Best For: LED Flashers, PWM Motor Control, and Tone Generation.
SN74HC595N 8-Bit Shift Register IC (DIP-16) | Pin Expander
Turn 3 pins into 8. Running out of pins on your Arduino? The SN74HC595 Shift Register allows you to control 8 separate outputs (like LEDs or LCDs) using only 3 digital pins on your microcontroller. You can even daisy-chain them to control hundreds of outputs!
-
Function: Serial-In, Parallel-Out (SIPO).
-
Channels: 8 Outputs per chip.
-
Voltage: 2V - 6V DC.
-
Best For: LED Chasers, 7-Segment Displays, and LED Cube Projects.
