Can anyone tell me the available pins for ESP8266 NODEMCU? I need to connect some sensors and I know that some pins are used by the Wifi chip. So which of them are available? I saw a diagram in the internet but couldn' t figure out what is and what is not available.
Great link! GPIO 4, 5, 12, 13, 14 can be used with normal commands? I saw that 4, 5 are L2C and the rest are SPI and I am not sure if that need a special treatment.
