Bi-Directional Voltage Level Shifter - RT-NVT2008
Robothings
RT-NVT2008
This is a voltage level shifter/translator. It is capable of connecting the SPI/I2C communication buses or digital signals with different voltage standards. I.e. you can connect the 5V logic Arduino to 3.3V/1.8V logic sensors or to connect 3V3 IO of Digilent Analog Discovery to 1.8V/5V sensors.
This board has 8 bidirectional digital channels, SOT23-5 LDO voltage regulator for low side voltage and LEDs indicating supply voltages (low and high voltage).
Voltage regulator can be used as power supply for connected sensor.
Permitted voltage difference between devices is limited by equation (VREF_B - VREF_A)>= 1V. Where VREF_B is external supply voltage, VREF_A is the LDO regulator voltage.
Table 1. Choosing the LDO voltage.
This board have an optional RA and RB 0402 pull-up resistors. More one choosing proper value of the pull-up resistors can be found in NVT2008 Datasheet. We assemble 1k Ohm RB resistors for you.
This RT-NVT2008 has assembled 3V3 fixed voltage regulator in the SOT23-5 package. You can switch freely LDOs according to table 1.
Example of using the RT-NVT2008.

RT-NVT2008 PCB has place for two 2.54 pin headers connector.
By adding this accessory we will assemble two straight pin headers.
Otherwise you will get two unassembled pin headers with the product.
