Key specifications
Model: JKMF403 (Renkforce)
Manufacturer MPN: RF-4599688
EAN: 4064161148472
Quantity: 40 single-conductor jumper wires
Length: approx. 30.0 cm (various colors)

How to use
Select the required jumper wires by color and length, then insert one end into the source pin or header and the other end into the target pin, header or breadboard hole. For secure connections on development boards such as Arduino, Raspberry Pi or Banana Pi, ensure pins are aligned and fully seated. Use multiple jumpers to route signals, power and ground as needed while avoiding crossing or excessive tension on the wires.
Usage recommendations
For reliable results, use jumpers of different colors to identify signal, power and ground lines. Inspect connections for firm seating before powering your circuit and avoid bending wires sharply near the contact points to prolong cable life.
