It provides a reset button, a STEMMA QT / Qwiic connector, a prototyping grid, and double-row socket headers — all with no soldering required when used with a Pico H or Pico WH. The double-row sockets give you an extra row of pins alongside each Pico pin, so you can poke jumper wires directly in without a breadboard. The hollow socket design also allows plug-through from the back using Pico Stacking Headers. All pins are clearly labelled on the silkscreen. Key Features 2×20 Double-Row Socket Headers – Pre-soldered; plug in your Pico with an extra row of sockets per pin for easy wire connections Reset Button – Right-angle button at the board edge for quick restarts STEMMA QT / Qwiic Connector – Right-angle JST SH for I2C on GPIO 4 (SDA) and GPIO 5 (SCL), with 4 extra breakout holes for re-assignment Prototyping Area – 3-hole connected strips in the centre (traces cuttable); duplicate hole pads next to every Pico pin for solder-jumpering Power Rails – Dedicated 3.3V strip and ground strip near the reset button; ground pads marked with white silkscreen 4 Mounting Holes – For attachment to an enclosure or underplate Gold-Plated Pads – For reliable soldering Hollow Socket Headers – Connect through the back with Pico Stacking Headers if needed Also Consider Proto Doubler PiCowbell – Two-slot version with LiPo charging for Pico + one PiCowbell accessory Proto Tripler PiCowbell – Three-slot version with LiPo charging, EYESPI, and NeoPixel Tip: No I2C pull-up resistors are included, but most STEMMA QT / Qwiic breakouts have them built in. Ideal For Solder-free Pico prototyping with easy pin access Adding I2C sensors and breakouts via STEMMA QT Quick breadboard-free builds and one-off projects Base plate for PiCowbell Doubler and Tripler setups Package Contents 1× Adafruit Proto Under Plate PiCowbell (assembled with double-row socket headers, reset button, and STEMMA QT connector) Note: Raspberry Pi Pico is sold separately. Use a Pico H or Pico WH for a fully solder-free setup. **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCQRRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--7303d308831aa5a73484ab356e9e6b666c7f6866/image_d42a07a3-a6ee-4609-8779-c923b02ec2c6.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCQhRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--2201b5a2cd9402639b21fdf1ecb0073a20613346/image_b80f69c6-6ea5-423f-a426-5ae5fa73ec2e.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCQxRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--6195af7ca590d7dac8ea717a7c71f27ef6fb6f8a/image_5fcf3bf1-50d6-47fb-ae57-25e594da9798.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCRBRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--7a93e2465a0386784b6e85d6bc26acde547b9bec/image_5da0f942-759f-4ef6-b607-761c9f585dd1.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCRRRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--a12d24ccbda98e580d234e7614b9522beaec39b1/image_ddd61629-7e9b-41d3-91c5-ea2ac1e429fd.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCRhRJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--674c5ecb5f233f0d036c2c560ae3ed9f9923c843/image_fb3bef2c-a928-4ddb-ae84-15714826fae5.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).
