#95864 I have an abundant supply of Robotdyn ESP8266-Pro modules I use for applications with I2C LCD displays.
On a LittleFS.h discussion page this morning, using a NodeMCU ESP8266 module, I noticed the author is using port D1 as SCL and D2 as SDA for his LCD display. Here https://www.hackster.io/Neutrino-1/littlefs-read-write-delete-using-esp8266-and-arduino-ide-867180

The NodeMCU pictured has the same labeled ports (D0, D1, D2, D3) as does the ESP8266-Pro module.

Could I also use the ports D1 as SCL and D2 as SDA on the ESP8266-Pro module?
And not declare which ports are to be used for the SCL and SDA?
Looks like the author's code doesn't contain a
Code: Select alllcd.begin(SDAport, SCLport);
to declare which ports are used for SCL and SDA. only the
Code: Select alllcd.init();

statement.
