1. Female Wire Bundles / Receptacles

Female 0.1" receptacles plug into the male headers used on OT-Hobbies boards. Many devices, such as R/C servos and some sensors, are made with such receptacles. For general use, these can be wired to any other devices connected to the boards. They can be made from individual parts, or pre-made cables can be cut into pieces for use.

They are very good for making permanent and reliable connections to controller boards.

  • adafruit 266 - $6.95.
  • Maker Shed - $5.95.
  • female crimp pins - $5.95/100.
  • 1x3 receptacles - $0.79/25.
  • misc bundles.

    2. Male Wire Bundles

    In general, jumper wires with male connector pins, such as plug into regular Arduino female stacking headers, are much less useful than those above. They are good for making temporary jumper connections, but not for making permanent connections.

    They easily fall out, and the round pins do not make very reliable connections with the spade terminals in the typical Arduino female headers. If male jumper wires are used, it's better if they have "square" pins.

  • adafruit 153 - $6.00.
  • Maker Shed - $8.99.

    3. Male Headers - Used to Make Female-Female Interconnects

    breakable male header

    Arduino female stacking headers are convenient for mounting shields, but difficult to make permanent connections to otherwise. One method for making a robust, semi-permanent connection is to use a male header (as shown at right) inbetween Arduino stacking headers and connection wires with female receptacles (as shown in section 1 above).

    A pin length of 6 mm [1/4"] on both sides of these headers is long enough to securely seat female receptacles, but don't get the kind that have one side with a short pin [ie, 3 mm = 1/8"].

  • pololu 1065 - $1.49.
  • adafruit 400 - $3.00, extra long pins.

    A slightly more permanent interconnect can be made by soldering wires to one side of the male headers shown here.

    4. Servo Extension Cables

    These are common market products, and can be cut and used to connect devices
    to male headers, or used to extend existing cables.

  • adafruit 972 - $1.95.
  • Parallax - $0.80.

  • 5. Arduino Stacking Headers

  • adafruit 85 - $1.95.
