SKU CH-J4MY-430TB

Five 20 cm colourful jumper wires with 2.54 mm female headers for solderless breadboard connections

  • TypeHI - Electrical & Industrial Wire
  • 20 cm length reaches across standard breadboards
  • Female-to-female connectors plug straight onto 2.54 mm pin headers
  • Copper-plated cores carry signals with low resistance
  • Five colour-coded wires keep circuits organised
  • Light 24 g pack adds negligible weight to projects

Female-to-Female Breadboard Jumpers

These five solderless jumper cables connect 2.54 mm pin headers on breadboards, PCBs or PC motherboards. Each wire is approximately 20 cm long and uses copper-plated conductors for reliable signal transfer. The colourful insulation helps identify connections quickly during prototyping.

Sustained-Use Reliability

Copper-plated contacts maintain low resistance across repeated insertions and removals without soldering. The flexible insulation resists fatigue when wires are routed around components or repositioned during debugging sessions. All five cables share the same 2.54 mm pitch so they stay aligned on standard header rows.

2.54 mm Pin Spacing Compatibility

The single specification that determines fit is the 2.54 mm pin spacing; these jumpers only work with headers built to that pitch. Builders using finer or wider header grids will need a different connector type. No other cable length or pin count is included in this pack.

Questions about this item

How much heat or power loss should I expect from the 2.54 mm copper-plated jumpers when they run continuously?

The copper-plated conductors at 2.54 mm spacing add negligible resistance, so heat and voltage drop stay minimal even with all-day use.

What pin headers must my board already have for these female-to-female cables to connect?

Your board needs standard 2.54 mm pitch male pin headers; the jumper sockets press directly onto those pins.

Will the 20 cm length reach between an older 2.54 mm header and a newer module on the same breadboard?

At 20 cm each, the five colour-coded wires give enough slack to bridge typical breadboard distances while keeping the 2.54 mm connection secure.
