## Customer Reviews

### ⭐⭐⭐⭐⭐ Really straightforward. Love how it hooks up.
*by P***R on January 2, 2022*

Between the images printed on the circuit board (showing which terminals were normally open vs normally closed) and the top reviews here (for basic code to turn it off/on), it was super straightforward to get this working. The metal standoffs included are really nice, and I love how this just sits cleanly on top of the raspberry pi. It includes an extra screw, at least the tiny ones. It worked immediately without any trouble. The wire connections are nice too.I did have to pull up some updated code for controlling the GPIO pins - no fault of the product, I'm just going off of the other amazon reviews b/c I don't want to wait for the seller to send over example code. Here's what I used to make it turn off and on (other comments have the GPIO pin numbers correct):echo 20 > /sys/class/gpio/exportecho out > /sys/class/gpio/gpio20/directionecho 0 > /sys/class/gpio/gpio20/value # onecho 1 > /sys/class/gpio/gpio20/value # offecho 20 > /sys/class/gpio/unexport # cleanup

### ⭐⭐⭐⭐ Good, but confusing labeling
*by J***H on April 13, 2019*

I needed exactly 3 relays to use with my Pi, so this was a perfect design. The only real problem is their absurd labeling that does not match the Pi's pin numbers or GPIO numbers. The P25, P28, and P29 are labeled on the 40-pin header of the HAT, but do not line up Pi pins 25, 28, 29, nor GPIO 25, and there is no GPIO 28 & 29 on the Pi. For anyone wanting to use this, here's what the pins actually are:P25 = GPIO26, Pin 37P28 = GPIO20, Pin 38P29 = GPIO21, Pin 40

### ⭐⭐⭐⭐⭐ Really nice board! A little more expensive than some stand-alone ...
*by R***Y on July 26, 2017*

Really nice board! A little more expensive than some stand-alone relay boards, but for Raspberry Pi, this is the best!The board is very high quality, well made, not junk like some others.I'm using it with OctoPrint to control camera lights and cooling fans for my 3D printer. Works really well!
