Bidirectional Logic Level Converter is a Four-Channel Device which can be used for Voltage Level Shifting between two devices.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 'H' pin, low voltage (3.3V for example) to 'L', and ground from the system to the 'GND' pin.

The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. The board can be control with a serial data from any microcontroller 0-100% dimming or ON/OFF control.Board also providing an option for connecting bluetooth and controlling tha loads from any smart apps. Mains power (230v) completely isolated from the microcontroller.

A 4x4 matrix keypad requiring eight Input/Output ports for interfacing isused as an example. Rows are connected to Peripheral Input/Output (PIO) pins configured as output. Columns are connected to PIO pins configured as input with interrupts. In this configuration, four pull-up resistors must be added in order to apply a high level on the corresponding input pins.

Note: The color of the PCB may vary. However the circuit/pinout of the PCB will remain same.

The board has only one  relay driven by TTL circuit and MCT2E IC for isolation purpose.The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control relays. Relay can switch varierty of AC or DC high voltage, high current 20A,loads working at 110V or 230V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.This 8-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.
