Product Overview
The 400-point breadboard (often called the “Half-Size” board) is a staple for every electronics lab. It provides enough room for a microcontroller and several supporting components without taking up too much desk space. The board features a standard double-strip layout for ICs and two dedicated power rails on the edges for organized voltage distribution.
Layout & Power Connectivity
Dual Power Rails: Located on the sides, clearly marked with Red (+) and Blue (-) for VCC and GND.
Component Area: 30 columns of 5 connected holes on each side of the center divider.
IC Center Notch: Optimized to fit standard DIP ICs and microcontrollers like the Arduino Nano or ESP32-S series.

Key Features
Compact Efficiency: Large enough for complex sensor circuits but small enough for portable prototypes.
Alphanumeric Grid: Clearly labeled rows and columns (A-J / 1-30) for easy circuit mapping and troubleshooting.
Modular Design: Side interlocking tabs allow you to snap multiple boards together to expand your workspace.
Strong Grip: Internal spring clips ensure solid connections with 20-29 AWG wires and components.
