Logic level converter I2C PCA9306 - SparkFun BOB-15439

The module allows communication between circuits using different voltage levels for I2C and SMBus. PCA9306 converts voltages from lower range from 1.2 V to 3.3 V to higher range from 1.8 V to 5 V.

Leads are solder fields, allowing to solder goldpin connectors (raster 2.54 mm). Thanks to them it is possible to connect the chip to contact board board or main module (eg. STM32Discovery or Arduino) using wires.

SCLx and SDAx bus outputs are connected to corresponding pins on the board. VREFx is the reference voltage for the given side. GND is system ground, NC should be left unconnected. After proper connection the module will start bi-directional conversion

Kit does not include goldpin stripIt can be purchased separately.
