This is a breakout board for the PCA9306 dual bidirectional voltage-level translator. Because different parts sometimes use different voltage levels to communicate, voltage level translators can be the key to making different parts play nice.
The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator that\'s operational on the low side from 1.0 V to 3.6 V and on the high side from 1.8 V to 5.5 V. Simply apply your low- and high-side reference voltages to the VREF1 and VREF2 respectively, connect your I/O and drive the Enable pin high to open bidirectional voltage translation without the use of a direction pin!
