ALLNET ALL-BRICK-0008 NPN Transistor Module for Arduino Raspberry Pi

The ALLNET ALL-BRICK-0008 is a compact NPN bipolar junction transistor (BJT) module designed for low-power switching, signal amplification, and digital logic interfacing. It integrates a general-purpose NPN transistor (e.g., BC547 series equivalent) on a breadboard-friendly PCB, making it ideal for prototyping with Arduino, Raspberry Pi, and other microcontroller development boards.

Advantages

This transistor module simplifies circuit design by providing a pre-mounted NPN transistor with a 3-pin header (VCC, GND, Signal) for easy connection. Its open-collector output allows direct control of loads up to 45V and 100mA, while the wide operating voltage range (3.3V-5V) ensures compatibility with both 3.3V and 5V logic systems. The compact size (32x14x10 mm) and through-hole mounting make it perfect for solderless breadboards and permanent projects.

Suitable for

• Low-power switching applications (e.g., driving relays, LEDs, small motors)
• Signal amplification in sensor circuits
• Digital logic level shifting and interfacing
• Educational projects and prototyping with microcontrollers

Recommendations

For best performance, use a base resistor (typically 1kΩ to 10kΩ) between the microcontroller output pin and the module's signal input to limit base current. Ensure the load connected to the collector does not exceed the maximum ratings (45V, 100mA). This module is not suitable for high-power or high-frequency applications.
