Review on ESP-01 Wireless Transceiver Board 3.3V - πŸ“‘ 4Pcs ESP8266 Serial WiFi Module for Arduino (Updated) by Keith Maynard

Revainrating 5 out of 5

Fascinating computer components

These things are so ridiculously addictive it's crazy. Extremely versatile and helpful, beyond any review I can write. I have small sensors connected to GPIO2 all over my house. The only thing that irritates me is the red power indicator. Had to break it off the board and it would have been nice to use the hibernation feature but had trouble connecting GPIO 16 to the former. but i love her Next time I might order the ones that have access to more ports, but for now and for real small jobs they're great!

Pros
  • Don't waste too much time
Cons
  • Some troubles
