JOY-IT RB-CON+01 GPIO Breakout Expansion Board for Raspberry Pi

Connecting sensors, actuators, or industrial equipment to a Raspberry Pi often means dealing with fragile jumper wires and unreliable connections. The JOY-IT RB-CON+01 eliminates that hassle by breaking out every GPIO pin to sturdy screw terminals, so you can wire up your projects securely and permanently.

Who is it for

Makers, prototypers, and industrial users who need a robust and reliable way to connect external devices to a Raspberry Pi 2B, 3B, 3B+, or 4B. Ideal for home automation, sensor integration, and control systems where vibration or movement could loosen standard connectors.

Main features

• Breaks out all 40 GPIO pins to clearly labelled screw terminals
• Additional terminals for 3.3V, 5V, and GND power rails
• Directly mounts onto the Raspberry Pi GPIO header – no soldering required
• Durable PCB with metal screw terminals for secure, vibration-resistant connections
• Compatible with Raspberry Pi 2B, 3B, 3B+, and 4B
