I connected it with sct-013 and with an "easy" online tutorial (calibration is a bit painful) I have a power consumption meter connected to the home assistant

A little cheaper it would be, better it would be. However, the board is very nice, you can do many different projects if you combine it

I used it as a guide for addressable LED strip. Using wled for drivers, the process was very simple and full of fun!

Very good, cheap, and greatly reduces the cost of robotics, STEM, etc. projects compared to Arduino. Instead of buying screens, bulbs, switches, trimmers, etc., you can turn the NodeMCU into a router-server, connect it to your mobile phone via its WiFi, and control cars, robotic arms, temperature-humidity, etc.
I installed MicroPython to easily transfer projects to more powerful boards like the ESP32, Raspberry Pi Zero, etc.
Additionally, it can be powered by voltages ranging from 7 to 12V (theoretically up to 20V), eliminating the need for power banks, voltage regulators (7805), or step-up-down converters. Not all boards have built-in voltage regulators.

The product was excellent. I was completely satisfied! The staff at the store were very communicative.

Good but it requires those old drivers that if you don't know what to do, it drives you crazy...

Average. I would recommend if you want a "wifi jammer" or wifi repeater, to buy the esp8266 cp2102 NodeMcu (amica). Because it is smaller and faster.

It does what it was designed to do. Perfectly compatible for Arduino projects. Excellent transmission. Satisfactory bitrate. Simply handles temperature that was corrected through software! If referred to as a jammer, its value and the code of every developer are underestimated.
