Product Details

Bi-Directional Voltage Level Shifter - RT-NVT2008
Mfr. Part #
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


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

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. We assemble 1k Ohm RB resistors for you.

Low Voltage LDO regulator

This RT-NVT2008 has assembled fixed voltage regulator in the SOT23-5 package depend on your choise. You can switch freely LDOs according to table 1.

Connecting module

Example of using the RT-NVT2008.

Select, if you have your own SOT235 LDO.

How it works

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds. Please see our FAQ page for more details on our billing process.
