A solid solderless breadboard for prototyping circuits without soldering. The 400-point suits compact builds and learning; the 830-point gives you more room for bigger projects with multiple modules or sensors side by side. Nickel-plated spring clips hold component leads and wire firmly, and the power rails run the full length of the board.
- 400 or 830 tie points — pick the size above
- Nickel-plated phosphor bronze spring clips
- Lettered rows and numbered columns for easy orientation
- Full-length power rails (red/blue) on each side
- 2.54mm pitch — fits DIP ICs and dev board pin headers
- Interlocking tabs — clip boards side by side to expand
- Adhesive backing for bench or enclosure mounting
- No soldering — rearrange circuits instantly
Specifications
What's in the box
Single board. Adhesive backing pre-applied on the underside.
Great for
Getting started
- Orient the board
Rows are labelled A–E and F–J either side of the centre gap. Columns number across the board from 1 to 30 (400pt) or 1 to 63 (830pt).
- Understand the connections
All five holes in a row (A–E or F–J) connect within each half-strip. The centre gap separates the halves — DIP ICs straddle this gap perfectly.
- Use the power rails
The long red (+) and blue (–) rails on each side run the full length of the board. Connect your supply here and use short jumpers to distribute power to your components.
- Insert components and wires
Push leads straight in until they seat firmly. Pull straight out to remove — wiggling can bend fine component leads.
Common questions
400 or 830 point — which do I need?
400-point for compact circuits, single modules, or learning exercises. 830-point for bigger builds with multiple modules or sensors. When in doubt, go 830.
Will standard DIP ICs fit?
Yes. DIP chips (555 timers, 74HC-series, ATmega, op-amps) straddle the centre gap with each row of pins in a separate half-strip. The 2.54mm pitch matches through-hole DIP components exactly.
Can I connect two boards together?
Yes. The interlocking tabs on the sides clip boards together to create a wider work surface — useful for bigger projects or for adding extra power rail space.
Will Arduino or ESP32 dev boards fit?
Yes, all standard 2.54mm pin-header boards fit. Note the 38-pin ESP32 is wide and covers most of an 830pt board — many users connect it via jumper wires rather than plugging in directly.
Good to know: Breadboards are for low-voltage electronics (typically 5V and under). Not rated for mains voltage. Keep wires short — long wires at high frequencies can act as antennas and cause interference.
