Logic Level Converter - 4 Channels Bi-directional

C1330

Elmwood Electronics has stopped accepting orders. This product might be available at PiShop.ca. Please check this blog post about our recent team merger.

Have you tried connecting a 3.3V device to a 5V system, or the other way around? It can be a challenge!
This Logic Converter makes it easier! Despite its small size, it converts 5V signals to 3.3V (and vice versa) effectively and at high speed. This converter also works with 2.8V and 1.8V devices. Each level converter is capable of converting 4 pins on the high side to 4 pins on the low side, 4 channels for each side.
It's also Breadboard friendly! Can be used with normal serial, I2C, SPI, and any other digital signal.
NOTE: does not work with an analog signal.
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 (2.8V for example) to 'LV', and ground from the system to the 'GND' pin.


Pins are labeled as Receiver and Transmitter:

These labels are relative to the board. Example:


3.3V GPS module                   LC04A                          5V Microcontroller System
3.3V Tx pin                         LT1 ---------- HT1             5V Rx pin
3.3V Rx pin                       LR1 ---------- HR1             5V Tx pin

Don't forget the '+' for 3.3V and 5V, also the ground for both sides.

A digital logic 1 (high) going into the LT1 pin on the 3.3V side will show up on the HT1pin on the 5V side as 5V. This LC04A is bidirectional; it can be used as a I2C communication line too.

The LC04A board comes with two 6 way header pin, unsoldered,  to provide flexibility of use.
