The Adafruit Proto Tripler PiCowbell gives your Raspberry Pi Pico or Pico W three side-by-side socket slots — plug in your Pico and up to two PiCowbell accessories with no soldering or stacking headers required. It also includes LiPo battery charging, a power switch, reset button, STEMMA QT connector, EYESPI display connector, a built-in NeoPixel, and prototyping areas.

Each socket has a double row of pins so you can poke jumper wires directly in without a breadboard. The hollow sockets also allow plug-through from the back using Pico Stacking Headers. All pins are clearly labelled on the silkscreen.

Key Features

• Triple 2×20 Socket Headers – Pre-soldered; plug in a Pico plus two PiCowBell accessories with an extra row of sockets per pin
• LiPo/Li-Ion Charging – JST PH connector with 500 mA charge rate (adjustable to 250 mA via jumper); orange LED while charging, green when complete
• Alkaline/NiMH Support – Cut a jumper to disable the charger for 3×AA or 3×AAA battery packs
• Power Slide Switch – Connected to Pico Enable pin to disable the 3.3V supply
• Reset Button – Right-angle button at the board edge
• STEMMA QT / Qwiic Connector – JST SH for I2C on GPIO 4 (SDA) and GPIO 5 (SCL), with extra breakout holes
• EYESPI Connector – 18-pin FPC for SPI displays with SD card and touchscreen support
• Built-In NeoPixel – On-board RGB LED for status feedback
• Prototyping Area – 3-hole connected strips in centre areas, plus duplicate hole pads next to nearly every Pico pin
• Power Rails – Dedicated 3.3V and ground strips; ground pads marked with white silkscreen
• 4 Mounting Holes – For attachment to an underplate or enclosure
• Gold-Plated Pads – For reliable soldering

Also Consider

• Proto Doubler PiCowbell – Two-slot version if you only need one PiCowbell accessory

Ideal For

• Solder-free multi-accessory Pico projects
• Battery-powered portable Pico builds with display output
• Prototyping with easy pin access via extra socket rows
• Combining multiple PiCowbell accessories with EYESPI displays
