Detailed Description:

Elevate your electronics projects with the expansive and versatile 840-Point Large Solderless Experiment Board, often recognized as the MB-102 breadboard. This generously sized, reusable prototyping platform is an indispensable tool for hobbyists, educators, and engineers, especially when tackling more complex circuits that require ample space for numerous components and intricate wiring. It allows you to rapidly build, test, and modify electronic designs without the permanence or fuss of soldering.

The 840-point breadboard gets its name from its substantial number of connection points: typically 630 tie-points in the main component area and 200 tie-points distributed across two dedicated power rails (100 points each) along the sides. These power rails are crucial for efficiently distributing VCC and GND to various parts of your circuit, simplifying power management. The main area features rows of 5 electrically connected holes, separated by a central groove, perfectly designed to straddle Dual In-line Package (DIP) integrated circuits (ICs).

Constructed from durable ABS plastic with internal nickel-plated phosphor bronze spring clips, this board ensures reliable electrical connections for solid-core wires (typically 20-29 AWG) and most through-hole components. All holes are spaced at the industry-standard 2.54mm (0.1-inch) pitch, guaranteeing compatibility with virtually all common electronic parts. The 840-point breadboard is compatible with popular development boards like Arduino, Raspberry Pi, ESP32, and STM32, making it ideal for large-scale microcontroller projects, educational kits, and rapid prototyping before final PCB design. Many versions also feature a self-adhesive backing for secure mounting and can be daisy-chained with other MB-102 boards for even larger circuit assemblies. For anyone in Pune, Maharashtra, India, or elsewhere looking to build, experiment, and learn efficiently with electronics, this large solderless experiment board is a fundamental and invaluable asset.

The MB-102 Breadboard is a large 840-point solderless prototyping board used for temporary circuit building, allowing quick design and testing of electronic circuits without soldering. It is made of high-quality ABS plastic with phosphor bronze nickel-plated spring clips for reliable and firm connections.

The board features 2 power rails on each side, 630 tie-points in the main area, and two 100-point power buses, offering ample space for ICs, resistors, capacitors, jumper wires, and other components. Designed to be reusable and stackable, it is perfect for Arduino projects, microcontroller prototyping, STEM education, and electronics learning.
