Overview


This module is useful for communicating between 2 tracks that work at different logic voltages. For example, a sensor that works at 3.3 V and does not tolerate 5 V on logic pins, requires the use of this two-way level translator to communicate with an Arduino UNO-compatible development board.

This product has 4 individual channels, which means it is ideal for SPI communication protocols, I 2 C.


Specifications

  • Supply voltage LV: 1.4 V to 3.6 V;
  • Supply voltage HV: 1.65 V to 5.5 V;
  • Max. Current / channel: 50 mA;
  • Maximum LV / HV current: 100 mA;
  • Compatible communication protocols: SPI, I 2 C, UART;
  • Dimensions 16 mm x 16 mm;


Instructions for Use


If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The CJMCU bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'HV' pin, low voltage ( 3.3V for example) to 'LV', and ground from the system to the 'GND' pin.


Make the hardware connections.

On the PCB board, the meaning of the pins (LV1-4, LV / HV, GND, and HV1-4) is marked. On the LV side, the low-voltage product (LV = LOW VOLTAGE) is connected, and the HV-connected product connects the product at a higher voltage (HV = HIGH VOLTAGE).

To supply the transducer, you need to apply a voltage to the HV pin and LV pin. Also, be sure to connect the GND pins to GND for each source.

Fast bidirectional reliable

Bidirectional 4-channel level convertor between 5 and 3.3 V. Runs on 1MHz+.

    Works great. does exactly what it's supposed to do.

    I needed these to use with an Arduino MKR 1010, because the MKR can't do 5V on the inputs. I am quite pleased with these.

      Great converter

      Great unit for converting from 3V Pi to 5V sensors/Adruino. All units worked out of box. Priced right.

        Used on a Raspberry pi

        Very easy to setup! Solder the pins, connect your ground and 5V to HV and 3.3V to LV then it's ready to go.

          Seems to be reliable

          Worked well for an I2C project. Project continues to work reliably converting 5 VDC to 3.3 VDC communicating state data

            Great Buy!

            Great product, comes with multiple for multiple projects at an amazing price! They work very well and am happy to have purchased them.

              Worked well for driving WS2812B LED strips from an ESP32.

              Got glitches trying to control multiple WS2812B LED strips with an ESP32; converting the control data from 3.3V to 5V with this module cleared them up completely.

                  Convert I2C interface for raspberry pi

                  Wired up three of these boards and they perform well. Converting Raspberry Pi I2c (3.3v) to LCD 1602 (16x2) displays that require 5 volts. Works well. Small size so it can be attached to the back of the LCD board.

                    Worked perfectly

                    I'm using one of these with a PI Zero to control some 5 volt LEDs. The device works perfectly.
