Create reusable solderless circuits with the ELEGOO 3-Pack 830-Point Breadboard Kit. Each full-size board gives students and makers room to assemble, test and revise low-voltage electronic prototypes without soldering.
Every board has 830 tie points: a 630-point terminal area and two 100-point distribution strips that provide four power rails. Printed letters, numbers and colored rail guides make nodes easier to trace, while the center channel accepts compatible DIP integrated circuits. Standard 2.54 mm or 0.1-inch spacing works with many through-hole components and jumper wires.
Build LED indicators, button inputs, transistor switches, sensor interfaces, timing circuits and controller experiments. Families can leave several weekend projects assembled, homeschool programs can demonstrate series and parallel circuits, and STEM classes can give each team a separate board. Makers can keep one board for power, one for control and one for the circuit under test.
The solderless layout can be rewired as a design changes. Self-adhesive backing can secure a completed prototype to a clean flat surface, and side clips help align compatible boards for larger layouts. Wide ESP32-style boards may cover nearby rows; placing the module between two breadboards can preserve access to its pins.
Use straight 21-26 AWG leads and insert parts vertically. Do not force oversized or bent pins, because damaged spring contacts can create intermittent connections. Verify which five-hole groups and power rails are internally connected, test questionable points for continuity and disconnect power before changing a circuit.
The package contains three 830-point breadboards. These boards are for temporary low-voltage prototyping, not mains wiring, high-current power distribution, permanent production assemblies or safety-critical circuits.
Component listing:
3pcs 830 tie-points breadboard

• THREE FULL-SIZE BREADBOARDS: Keep multiple circuits assembled at once, give each lab group its own board or connect compatible boards side by side for larger electronics, robotics and STEM prototypes
• 830 TIE POINTS AND FOUR POWER RAILS: Each board includes a 630-point terminal area plus two 100-point distribution strips, with printed letters, numbers and colored rail guides to make circuit tracing easier
• BUILD AND REWIRE WITHOUT SOLDERING: Insert resistors, LEDs, capacitors, transistors, sensors and jumper wires, then change connections as lessons or prototype designs evolve without soldering components in place
• SELF-ADHESIVE BACKS AND SIDE CLIPS: Peel the backing to mount a finished prototype on a clean flat surface, or align compatible breadboards with the side clips when a wider prototyping area is needed
• DESIGNED FOR 21–26 AWG LEADS: Use straight compatible leads and insert components vertically for reliable contact; package includes three 830-point breadboards only, with jumper wires, components and controller boards sold separately
