It also adds LiPo battery charging, a power switch, reset button, STEMMA QT connector, and a prototyping area.\n\nEach socket has a second row of pins so you can poke jumper wires directly in without breadboarding. The dual sockets are hollow, meaning you can also plug through the back using Pico Stacking Headers if needed. All pins are clearly labelled on the silkscreen.\n\nKey Features\n\n\nDual 2×20 Socket Headers – Pre-soldered; plug in a Pico and a PiCowbell side by side with an extra row of sockets per pin\n\nLiPo/Li-Ion Charging – JST PH connector with 500 mA charge rate (adjustable to 250 mA via jumper); orange LED while charging, green when complete\n\nAlkaline/NiMH Support – Cut a jumper to disable the charger for use with 3×AA or 3×AAA battery packs\n\nPower Slide Switch – Connected to Pico Enable pin to disable the 3.3V supply for low-power sleep\n\nReset Button – Right-angle button at the board edge\n\nSTEMMA QT / Qwiic Connector – JST SH for I2C on GPIO 4 (SDA) and GPIO 5 (SCL), with extra breakout holes for re-assignment\n\nPrototyping Area – 3-hole connected strips in the centre area, plus duplicate hole pads next to nearly every Pico pin\n\nPower Rails – Dedicated 3.3V and ground strips; ground pads marked with white silkscreen\n\n4 Mounting Holes – For secure attachment to an underplate or enclosure\n\nGold-Plated Pads – For reliable soldering\n\n\nI2C Configuration\n\n\nArduino (Philhower core) – Wire peripheral pre-configured for GPIO 4 and 5\n\nCircuitPython / MicroPython – Set SDA=4 and SCL=5 in code\n\n\n\nTip: No I2C pull-up resistors are included, but most STEMMA QT / Qwiic breakouts have them built in. Use a Pico H or Pico WH for fully solder-free setup.\n\n\nIdeal For\n\nSolder-free Pico + PiCowbell projects\nBattery-powered portable Pico builds\nPrototyping with easy pin access via the extra socket row\nCombining multiple PiCowbell accessories\n\n\nPackage Contents\n\n1× Adafruit Proto Doubler PiCowbell (assembled with dual socket headers, JST PH battery connector, slide switch, reset button, and STEMMA QT connector)\n\n\n\nNote: Raspberry Pi Pico, battery, and PiCowbell accessories are sold separately. If using alkaline/NiMH batteries, cut the \"disable charge\" jumper first.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1128,"title":"Default Title","sku":"AF-5906","mpn":"ADA5906","price":13.87,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":69,"option1":"Default Title"}]}
