- The CJMCU bi-directional logic level converter simplifies the connection between 3.3V devices and 5V systems, ensuring safe signal conversion in both directions. - This device effectively reduces 5V signals to 3.3V while simultaneously elevating 3.3V signals to 5V, addressing common compatibility issues. - Unique to this version, users can set high and low voltage levels for safe switching on the same channel, enhancing versatility and functionality. - The compact board requires two separate voltage sources for operation: connect your high voltage (e.g., 5V) to the 'H V' pin and your low voltage (e.g., 3.3V) to the 'L V' pin. - Each converter supports the conversion of 4 pins on the high side to 4 pins on the low side, featuring two inputs and two outputs for each voltage level, streamlining multiple connections. Applications: - Ideal for integrating low-voltage sensors or modules with higher voltage microcontrollers, ensuring seamless communication without damaging components. - Useful in robotics projects where different voltage components must interact, facilitating reliable data exchange. - Perfect for interfacing legacy 5V devices with modern 3.3V systems, preserving functionality while updating technology. This logic level converter is essential for anyone looking to bridge the gap between different voltage systems efficiently and safely.
