Cool story, right? We mention it because stacking headers are sort of like the wheel to the Arduino civilization - meaning this thing that’s incredibly simple, incredibly useful, but still so brilliant you’re amazed they didn’t exist before the day they started existing.  What are they for? Stacking.  You put the headers on top of your Arduino and then you can add shields like our Protoshield or our Motor Shield  or our Proto-Screwshield (pictured above) to get your Arduino doing all the cool things you want it to.  Our set includes 1x 10-pin header, 2x 8-pin headers, 2x 6-pin headers, and one 2x3 header. The legs are all 10.5mm long, so after PCB thickness (1.7mm) you have a height of 8.8mm - just enough to clear the Arduino's USB-B connector.  They’re also fully compatible with shields designed for Arduino R3 and the Leonardo.  For shields that don’t use the 10-pin header or 2x3 header, use the 6 or 8 pin ones. Some experimentation might be necessary to get these working.  For example: You can stack on top of a Proto Shield, but not if there is a breadboard on it You can stack on top of an Adafruit Motor Shield v2 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. You can't stack on top of our TFT or LCD shields Some shields use the ICSP (2x3) header in which case you may need to solder in the stacking 2x3 Really, the possibilities are endless, just keep in mind that you may need to do some adjusting of code to handle the multiple devices and that there may be pin compatibilities.     **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCa2RJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--41e9c3060bd5791972731858cb366919442d5ffc/image_7643401f-2ca6-4b7e-8784-c093f11e942a.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCbGRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--a025995db9880d1d4f0c6886aeceb2300f7da336/image_7254a7f9-2b1c-4d03-9a70-13b06b3f2f6b.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCbWRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--0e712a5edf0866debc6a0a09a9ec7e98d458b204/image_0caae23e-8c34-4850-a57b-c89264ceaac8.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCbmRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--a8df5304d4c923eb17d950e7d38ae0131fb00831/image_1feace36-2a92-4ff1-8738-6468328e886c.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
