I want to connect the TK1 via UART with my device.
A level shifter (3.3 V <-> 5 V) was used because TK1 works with logic level of 1.8V.
My device operates at 3.3V logic level, so for this scenario, it is 1.8 V <-> 3.3 V.
Before i test the connection, i would like to be sure that the connection is correct (see Image).
Could someone check my UART connection? Has anyone here such a level shifter used (3.3V <-> 5V)?
