4-Channel Voltage Converter Module for Multiple Data Lines, 2pcs Automatic Direction Sensing, 4 Separate Conversion Channels, Mixed-Voltage Controller

Automatic Two-Way Conversion: Direction sensing routes data in either direction between 3.3 V and 5 V circuits without a separate direction-control pin Confirmed Package Contents: The package includes the bidirectional voltage converter module and a packaging bag; controllers, connected devices, and wiring hardware are not included 4 Separate Channels: Distinct A-to-B paths let multiple data lines pass through the same PCB converter module for a coordinated voltage-shifting connection Defined Electrical Setup: Separate 3.3 V and 5 V supply inputs the two voltage domains, with pull-up resistors 50 kΩ or higher Mixed-Voltage Connection Tasks: Use the module for voltage matching between 3.3 V microcontrollers and 5 V devices or for SPI data across different circuit voltages
