Because some MCU development boards and devices work at 3.3V, and there are MCU development boards, equipment, sensors, etc. that work at 5.0V, so when the two need to communicate, there will be an inconsistency in working voltage, which makes users use It's not convenient. This product is designed to address and solve this problem. This module provides feasibility in different devices of 3.3V and 5.0V, and acts as a bridge.

Features:

• 2 channels of high-voltage and low-voltage logic logic bidirectional translation
• 2-channel high-voltage logic low voltage logic converted into a one-way conversion
• Module is compatible with the bread plate, can be directly plugged into the breadboard
• Instructions for use: [high voltage is 5V low voltage of 3.3V for example]
• HV 5V supply
• LV 3.3V power supply connection
• GND with negative power, two power commons
• RXI input 5v TTL, in RXO 3.3v TTL output
• TXI input and output 3.3V TTL, TXO input and output 5V TTL, TXI and TXO
