JEBHANNE 840Pcs Breadboard Jumper Wires Kit with 4 Solderless Breadboards, 14 Lengths 2-125mm Pre-Cut Flexible Connecting Cables & Storage Box for Arduino, Raspberry Pi, DIY Electronics Prototyping

Features

• COMPLETE PROTOTYPING BUNDLE IN ONE BOX — Includes 2× 830 tie-point and 2× 400 tie-point solderless breadboards plus 840 pre-cut jumper wires in 14 lengths (2mm to 125mm), a storage box, and tweezers. Everything you need to build your first circuit — no extra purchases required.
• 4 BREADBOARDS FOR ANY CIRCUIT SIZE — Two full-size 830-point boards for complex layouts, two compact 400-point boards for quick sub-circuits or parallel experiments. Boards interlock and expand, giving you the flexibility to prototype small, medium, or large designs side by side.
• 840 JUMPER WIRES — 14 LENGTHS, ZERO TANGLES — Pre-cut and pre-formed rigid wires in 8 vivid colors (red, orange, yellow, green, blue, purple, brown, white) organized by length from 2mm to 125mm in a dedicated storage box. Plug-and-play across boards with no clipping, stripping, or soldering needed.
• 100% SOLDER-FREE — EXPERIMENT INSTANTLY — The solderless breadboard design lets you insert, rearrange, and remove components in seconds. ABS plastic panels and tin-plated phosphor bronze contacts ensure stable connections rated up to 20–40mA, compatible with most through-hole components, sensors, and modules.
• DESIGNED FOR ARDUINO, RASPBERRY PI, STM32 & BEYOND — Perfect for beginners building their first LED circuit, students completing STEM coursework, engineers rapid-prototyping PCB designs, or educators equipping classroom lab kits. The included storage box keeps boards and wires organized between sessions.
