Features:

  • KEYESTUDIO ESP8266 WiFi Module can easily give any microcontroller access to your WiFi network.
  • Run out of the box that just simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers.
  • Supports APSD for VoIP applications and Bluetooth co-existance interfaces.
  • Contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.
  • This module has a powerful enough on-board processing and storage capability.
Good WiFi modules

These ESP-01 ESP8266 modules work great. The ESP-01 was the first of a plethora of ESP8266 based modules to be released, and even though it has the fewest pins available, it is still quite handy. I wanted these ones to add WiFi capabilities to a 3D printer using the esplink firmware. Now I can control my printer from across the room and don't need a cable attached.

Works as advertised!

Worked just like it's supposed to...I've been stocking up on Arduino gear, anything I can find, and having WiFi capability will definitely be interesting. Successfully connected and looking forward to experimentation with plugging my devices into the Internet of Things!

Great addition to the set.

I was working on a project that required the addition of a wireless web server, and this did just the trick. Most things are going to need web interface at one point or another which makes this module a great resource and cheap fix to boot. It's very easy to program and the quality of the chip itself was very good.

Nice WiFi modules and well priced.

Nice WiFi modules and well priced. I rarely have any issue with Keyestudio products. These modules work great with Arduino boards. Yes you can connect them to Other devices such asa Raspberry Pi 3B but it is a little superfluous considering they have built in WiFi modules.

Works great

I was able to power up these with a raspberry pi 3B. They work as expected. They shipped with the following firmware: AT version:1.2.0.0(Jul 1 2016 20:04:45) SDK version:1.5.4.1(39cb9a32) Ai-Thinker Technology Co. Ltd. Dec 2 2016 14:21:16 The esp8266 website has a good getting started article on how to wire these ESP-01s up to a raspberry pi. I then had to set the gpio pins to ALT0 and use picocom to communicate with them over /dev/ttyS0.

Worked from first attempt

Pretty seamless experience at least to get the board up and running (used Windows) and generic instructions for ESP8266 board with Arduino IDE. Maybe it is a new item, since it doesn't have any reviews.
