ALLNET ALL-BRICK-0013 Transistor 2 NPN Switching Module

The ALLNET ALL-BRICK-0013 Transistor 2 is a compact NPN bipolar junction transistor (BJT) switching module designed for electronic switching and digital control applications. Part of the ALL-BRICK system, it provides a convenient breadboard-friendly interface for driving low-power loads such as LEDs, small relays, buzzers, and logic level shifting.

Advantages

This module simplifies prototyping by integrating a pre-biased NPN transistor with a 3-pin header (VCC, GND, Signal). It operates at logic-level input voltages (3.3V-5V DC) and can switch up to 30V DC at 100mA, making it ideal for microcontroller projects with Arduino, Raspberry Pi, and similar boards. The TO-92 package ensures reliable performance across a wide temperature range (-40°C to +85°C).

Suitable for

• Driving LEDs and indicator lights
• Controlling small relays and buzzers
• Low-power motor control
• Logic level conversion (3.3V to 5V or vice versa)
• Educational electronics and prototyping
