ESP-01 WiFi Module

Addicting. Extremely versatile and useful.

These things are so ridiculously addicting it’s insane. I have them all over my house running small sensors wired up toGPIO2. Next time I may order ones that have access to more ports but for now, and real small jobs, they’re great!

Perfect small device for IoT!

These are great little devices to set up home automation or IoT. Very easy to get running if you have worked with Arduinos in the past.

All work Great

Everything works and ran Arduino Blink. Need to make sure you select the correct pin for LED (Sketch Programming).

Excellent price

If you know what your doing with these, they are fun. Every single one I got from this packaged has worked perfectly

You can do more than you thought with this device

First Time I used this and I love it. So much power in so litlle size.

Worked well and packaged properly

Exactly what they were supposed to be. I was able to program and use it right away. You’ll need a 3.3v power supply and cannot be used directly with a 5v Arduino. Had to add a level shifter to my project (interfacing with an Arduino mega) to communicate
