1. Female Wire Bundles / Receptacles
Female 0.1" receptacles plug into the male headers used on many embedded controller
They can be used for connecting boards together, and in addition, a lot of
devices like R/C servos and some sensors use such receptacles.
They are good for making permanent and reliable connections to controller boards.
Cables can be made from individual parts, or pre-made cables can be cut into pieces
and spliced for use.
adafruit 266 - $6.95.
Maker Shed - $5.95.
You can also make your own female cables using crimp pins and plastic receptacles
with 1 or more positions (lower row),
pololu - female crimp pins - $5.95/100.
jameco - female crimp pins - $0.15-0.19/each.
pololu - 1x3 receptacles - $0.79/25.
jameco - 1x3 receptacles - $0.29/each.
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
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.

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"].
- $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. Male Headers
|male header for pcb mounting|
Male headers with 0.1" (2.54 mm) pin spacing are the industry standard on embedded
controller boards. A pin length of 6 mm (0.23") above the pcb will securely mount the
female receptables mentioned above.
In addition, it's common for boards meant for robotics and other purposes to use 3-row
male headers with a signal-power-ground arrangement. This is the same as used on
many R/C servos and sensors, nowadays. It makes a convenient and compact wiring
bundle that carries both signal and power to the external devices. 3-row headers are
easy to make by positioning double-row and single-row headers next to each other.
jameco double-row headers - $1.09/72-position.
jameco single-row headers - $0.55/36-position.
5. 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.
