Bi-directional Logic Level Converter Module 5V-3.3V for Arduino/Raspberry Pi
These are really useful when working with different voltage levels and logic circuits.
We use these to configure serial connections from a raspberry pi GPIO ports to printer main boards like the MKS Gen L directly. This means there is no need to use a USB cable for octopi/octoprint.
Please note the pin headers are included but not soldered. This means you can easily solder wires directly to the board if required
From the manufacturer:
If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. 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.
