## Description

Review: A fun adventure with the Pi 3 B+. 4.75 stars! - These little things are awesome. Don’t let the pictures fool you, these babies are small! But they’re easy to read, feel fairly strong and sturdy, and fit beautifully (almost). I’ve got one of the new Pi 3 B+ boards and it’s got a fun little set of pins towards the bottom of the main pin rail for a POE hat (Power Over Ethernet). The boards are just a hair too long and run into the pins. I broke out my trusty razor blade to trim it up - but HOLY HECK!! These little guys are tough! I ended up having to gently cut it with some strong scissors. The board cut beautifully with out chipping or splintering. To recap: Great tool! Needs a slight mod for the 3B+. Glad I found these!
Review: Really well made, crisp clear lettering, very handy for RPi3+ GPIO - The pin outs on the GPIO are not organized very well. So for younger kids it really helps them to easily double check all the connections.before running a program.

### ⭐⭐⭐⭐⭐ A fun adventure with the Pi 3 B+. 4.75 stars!
*by J***C on March 29, 2018*

These little things are awesome. Don’t let the pictures fool you, these babies are small! But they’re easy to read, feel fairly strong and sturdy, and fit beautifully (almost). I’ve got one of the new Pi 3 B+ boards and it’s got a fun little set of pins towards the bottom of the main pin rail for a POE hat (Power Over Ethernet). The boards are just a hair too long and run into the pins. I broke out my trusty razor blade to trim it up - but HOLY HECK!! These little guys are tough!

### ⭐⭐⭐⭐⭐ Really well made, crisp clear lettering, very handy for RPi3+ GPIO
*by R***0 on February 14, 2019*

The pin outs on the GPIO are not organized very well. So for younger kids it really helps them to easily double check all the connections.before running a program.

### ⭐⭐⭐⭐ Thin, simple and effective.
*by R***S on December 25, 2017*

Thin, simple and effective. Great for development and learning about the GPIO pins. The pack comes with two as shown in a zip lock bag. They are a little brittle looking, so don't try to flex them (unless you want to snap them in two pieces!). They also stick out a few centimeters from the edge of the board, so obviously you won't be able to fit them into a case or use them in a final project. On the flip side, I think they could use a few more markings to indicate the orientation (like pointing out which side should be next to the USB ports), and a little bit of color to point out the power and ground pins.
