The Pi T-Cobbler Plus is a convenient GPIO breakout board designed to make Raspberry Pi breadboard prototyping faster, cleaner, and easier.
It connects the Raspberry Pi's 40-pin GPIO header to a standard solderless breadboard, providing clearly labeled access to the GPIO, power, I2C, SPI, UART, and ground connections.
Its distinctive T-shaped design provides additional space for clear pin labeling, making it easier to identify Raspberry Pi GPIO connections while building and testing electronic circuits.
This version is pre-assembled, so no soldering is required before use.

Easier Raspberry Pi Prototyping
Connecting components directly to the Raspberry Pi GPIO header can become difficult when developing larger circuits.
The T-Cobbler Plus brings the Raspberry Pi header connections directly onto a solderless breadboard, allowing electronic components and jumper wires to be connected in a more organized way.
This makes it particularly useful for:
- Circuit prototyping
- Sensor experiments
- Electronics education
- GPIO development
- Robotics
- IoT projects
40-Pin GPIO Breakout
The board is designed for Raspberry Pi models equipped with the standard 2 × 20 / 40-pin GPIO header.
It breaks out connections including:
- GPIO pins
- 3.3V power
- 5V power
- Ground
- I2C
- SPI
- UART
- Other multifunction GPIO signals
T-Shaped Design
Unlike more compact rectangular GPIO breakout boards, the T-Cobbler Plus uses a wider T-shaped PCB.
The additional PCB space allows the GPIO labels to be easier to read while working on a breadboard.
This is especially useful for beginners and educational applications where quickly identifying each Raspberry Pi pin is important.
Breadboard Compatible
The breakout board is designed to plug into a standard solderless breadboard.
Once connected to the Raspberry Pi using a compatible 40-pin ribbon cable, the GPIO signals become conveniently accessible alongside your breadboard components.
You can easily prototype circuits using:
- LEDs
- Push buttons
- Sensors
- Displays
- Buzzers
- Relays
- Transistors
- ADC/DAC modules
- I2C modules
- SPI modules
- UART devices
- Other electronic components
Raspberry Pi Compatibility
Designed for Raspberry Pi boards using the standard 40-pin GPIO header, including compatible models from:
- Raspberry Pi Zero series
- Raspberry Pi Model A+
- Raspberry Pi Model B+
- Raspberry Pi 2 Model B
- Raspberry Pi 3 series
- Other Raspberry Pi boards using a compatible 2 × 20 GPIO header
For newer Raspberry Pi models, verify the pinout, physical installation, ribbon cable orientation, and accessory compatibility before use.

Important Electrical Note
Raspberry Pi GPIO pins operate at 3.3V logic levels and are not 5V tolerant.
Do not apply 5V directly to a GPIO signal pin. When interfacing with 5V devices, use a suitable level shifter or interface circuit where required.
Always verify the GPIO pinout and ribbon cable orientation before powering the circuit.
Package Includes
Check the specific product package to confirm whether a 40-pin ribbon cable is included.
Important Note
Raspberry Pi, breadboard, jumper wires, sensors, and other electronic components are not included.
Always check the orientation of the 40-pin connector before powering your Raspberry Pi to avoid incorrect GPIO connections.
