Hallo,

Thank you for your answers.
This is a very nice board to build your own Arduino.

If used as an Arduino this pin would be digital pin 13 which normally has an LED connected to it.
OK, but normally a resistor is enough.
Why an extra FET?
Or is it better to use a resistor and a FET ( or an 2N2222 )?

Hallo,

Another question: Why is there a FET and a LED on SCKL?

Re: Serial I2C LCD 1602 Module (HCARDU0023)

Hallo, I am working with the smart LCD module in AT mode. When I wanted to print a variable it did not respond. After some trial end error I did find the following solution: Serial.println("AT+RC=0,2"); // Set cursor to first line position 3 Serial.println("AT+PR=Temperature"); Serial.println("AT+RC...
