Adafruit "Three Fives" 555SE Discrete Timer SMT Soldering Kit

The 555SE Discrete 555 Timer Kit from Evil Mad Scientist Laboratories is a surface-mount soldering kit designed to replicate the iconic NE555 timer integrated circuit at a transistor scale. This compact kit brings the timeless functionality of the NE555 timer to life, enabling you to explore its classic applications hands-on.

The kit includes all necessary components: a circuit board, high-quality resistors, and 2N3904 and 2N3906 transistors, ensuring a precise assembly. It also features an elegant aluminum display stand, complete with eight legs styled like SOIC-packaged integrated circuit pins for enhanced presentation.

Specifications:

• Surface-mount design with large 1206 and SOT-23 components.
• Includes 8 color-coded thumbscrew terminal posts.
• Printed assembly instructions for guided setup.

The 555SE is perfect for constructing various timer and oscillator circuits, thanks to terminal posts and solder points that allow flexible connectivity with wires, alligator clips, or solder joints. Unlike conventional chips, you can attach probes to observe the circuit's internal processes.

If you prefer hands-on practice with surface-mount technology or wish to advance your understanding of analog circuits, the 555SE kit offers a rewarding and educational experience. While similar to its larger, DIP-style counterpart, the Three Fives kit, the 555SE delivers an intricate, detailed, and engaging challenge that results in a functional 555 timer you can incorporate into countless projects.
