4-channel logic voltage level converter (OT3107)

This module can do voltage conversion for 4 channels in both directions between 1.8V, 2.8V, 3.3V and 5V digital signals, such as serial data, I2C and ISP (<2Mhz). For each channel an N-channel MOSFET is used in the following arrangement:
Anyone who connects their own circuit instead of a microcontroller should remember that at the input a connection to ground is needed between the pulses to represent a logical 0, and to get the output LOW. If nothing is connected to the pins, everything is in the HIGH state via the 10K pullup resistors.
Comes with separate headers
