3 Pcs ESP8266 NodeMCU, MELIFE CP2102 ESP-12E WiFi Internet Development Board Open Source Serial Wireless Module.

Bought these to use with WLED and control LED Pixels and they're working great. No issues.

While these have climbed in price steadily over the last two years, they're still a good value for what they provide and I haven't had any issues so far.

All three boards work well. One has a broken onboard LED, but it works fine otherwise. They are great little boards for IoT

Very pleased with the ESP8266. Have been using them for LED lighting without issue.
