RT-NVT2008

Product Description

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. ![RT-NVT2008 PCB Bottom](https://robothings.pl/img/RT-NVT2008/RT-NVT2008-PCB-VOLTAGE-LEVEL-SHIFTER-TRANSLATOR-BOTTOM-S.png) #### Constrains 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.* ![Permitted voltage differences between VREF_B and VREF_A](https://robothings.pl/img/RT-NVT2008/RT-NVT2008-PERMITTED-VOLTAGE-LEVELS-TABLE-TRANSLATOR.png) #### Pull-up resistors 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](https://www.nxp.com/docs/en/data-sheet/NVT2008_NVT2010.pdf). We assemble 1k Ohm RB resistors for you. #### Low Voltage LDO regulator This RT-NVT2008 has assembled 3V3 fixed voltage regulator in the SOT23-5 package. You can switch freely LDOs according to table 1. #### Connecting module Example of using the RT-NVT2008. ![RT-NVT2008 Connection diagram](https://robothings.pl/img/RT-NVT2008/RT-NVT2008-PCB-VOLTAGE-LEVEL-SHIFTER-TRANSLATOR-ROBOTHINGS-CONNECTION-DIAGRAM.png) #### Specification - Voltage shifter from 5V to 3V3 logic - Input voltage: 5V - Output voltage: 3V3 - Max. output current: 150mA - Optional 1k resistors for RB1...8 (Check options) - Holes for 2.54 pin headers (CA,CB) - Holes for ~AWG26 wires *Product page: [robothings.pl](https://robothings.pl/en/products/rt-nvt2008/)*
