Use these to stack shields on your Arduino! These are standard 6-pin, 8-pin and 10-pin 0.1" spacing female headers...with a twist! The pins are extra long which means you can use these to stack shields! The legs are 10.5mm (0.42") long, so after the PCB thickness (1.7mm/0.07") you have a height of 8.8mm (0.35"). Comes in a package of one 2x3-pin header, 2 x 8-pin headers, 2 x 6-pin headers and 1 x 10-pin header for full compatibility with shields designed for Arduino R3 & Leonardo.
Please note, not all shields use the 10-pin connector or 2x3 connector stacking header. For shields that do not use the 10-pin header, use the 2x6 and 2x8 headers.
Some experimentation might be necessary. Some examples:
You can stack on top of a Proto Shield, but not if there is a breadboard on it
You can stack on top of a Motor Shield, make sure you bend the electrolytic capacitors before you solder them in, so that they lay flat against the PCB
You can stack on top of a Wave, NFC/RFID, or GPS shield with no problems
You can stack on top of an Ethernet shield, but you'll need two sets of headers to clear the Ethernet jack.
Normal headers are included with all our shield kits but these are an upgrade for those that want to stack!
