Featured wire & cable categories
Breadboard & Dupont Jumpers
- Male–male & male–female jumper kits
- Ideal for breadboards, dev boards, and quick sensor tests
- Color-coded for easier troubleshooting in class or lab
Hook-Up Wire & Ribbon Cable
- Solid-core hook-up wire for perfboard jumpers
- Stranded hook-up wire for flexible connections
- Ribbon cable for tidy multi-signal runs
Pre-Crimped Leads & Power Cables
- JST battery/signal leads for Li-ion packs and sensors
- DC barrel power cables for 5V/12V adapters
- Great for making quick-disconnect harnesses in robots and enclosures
Tip: Use solid-core wire for short, fixed jumpers on perfboard, and stranded wire for anything that will bend or move (robot joints, doors, pump wiring).
Wire chooser (quick guide)
| Need | Good first choice | Notes |
|---|---|---|
| Breadboard prototyping | Male–male Dupont jumper kit | Fast, no tools needed; perfect for Arduino/ESP32 breadboard labs. |
| Module to breadboard or dev board | Male–female jumper leads | Use female ends on module headers, male ends into breadboard or Arduino pins. |
| Permanent wiring on perfboard | Solid-core hook-up wire (22–24 AWG) | Holds its shape and solders easily; keep runs short and neat. |
| Robot / moving parts | Stranded hook-up wire (20–24 AWG) | Flexible, resists breaking when frequently bent; ideal for motors and servos. |
| Multi-signal harness (e.g., encoder, keypad) | Ribbon cable + breakaway headers | Lets you keep many related signals flat and organized. |
| Battery & DC power in small projects | Pre-crimped JST leads / DC barrel cables | Safer, polarized connectors—harder to plug in backwards. |
Current ratings depend on wire gauge and insulation. For low-voltage hobby electronics (5–12V, under a few amps), 20–24 AWG is a common, safe starting point—always check datasheets for high-current loads.

FAQ
What’s the difference between solid and stranded wire?
Solid-core is a single stiff conductor, great for breadboards and perfboards. Stranded is many thin strands, more flexible and better for moving parts or long harnesses.
Which wire gauge (AWG) should I use?
For typical low-voltage electronics (LEDs, s
