About this product


Product overview

• Protect your GPIO pins against accidental shorts or voltage slips
• Each pin is protected by a 330Ω resistor and a Zener diode
• Some soldering is required
• Compatible with the Raspberry Pi Model A+ and B+ (not included)

What can I do with this extender?
Protect your Raspberry Pi from accidental shorts or voltage slips that can damage the board. The protector fits in between the board and your project and gives you access to all 40 GPIO pins. The extender connects a 330Ω resistor and a Zener diode to each pin, limiting excessive current and sinking any voltage up to 5V.

Does this extender require any assembly?
This kit requires some soldering. Once it’s assembled the extender fits on top of the GPIO pins on the Raspberry Pi board and can be connected into exactly as you would into the GPIO. The extender comes with a 200mm rainbow cable to connect it with.
