up resistors on SDA and SCL pin. I2C-
TRN comes with these two pull-up
resistors on both sides (total of 4
resistors) enabled from the manufacture.
It can be disabling when connect to I
bus that already have pull-up resistors by
remove the solder bridge on the “PU1” for
low-side, and “PU2” for high-side at the
bottom of the module.
When EN is high, the translator switch is
ON, and the SCL1 and SDA1 I/O are
connected to the SCL2 and SDA2 I/O,
respectively, allowing bidirectional data
flow between ports. When EN is low, the
translator switch is off, and a high-
impedance state exists between ports.
To
translation, solder a bridge
on “EN” at the bottom of the
