Frequently asked questions

How can I test the Wi-Fi connection?
Check the connection in REPL mode with `WiFi.status()`.

Does the module support multiple relays?
This module supports only one relay. To control more devices, consider the module with multiple channels.

What are the power requirements?
5V power supply, check the datasheet for detailed specifications.

Can I use this module with an Arduino Nano?
Yes, but make sure the Nano supports the ESP8266.
