    They do their job. HV to LV conversion is done with a resistor ladder, so the ratio is fixed. Used with I2C bus, WS2812 LEDs and TM1637 7-digit controller. Poor pin headers, they don't want to slide in my protoboard!

    It was my intention to "shift level" between the at 3.3 V operating Raspberry Zero, and a 16x2 LCD display with an i2C interface as daughter board, operating at 5 V. It does not work. Analysis as follows, first a test without level shifter: connected to the Raspberry, but using 3.3 volt instead of 5 volt for the display, everything works fine. (But due to 3.3 V the display is faintly lit). So software and hardware are OK. Now I inserted the level shifter, using both TXDs for SDA and SCL (RXD not used).
