Product description:
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.
Module features:
1. Two-channel high-voltage logic and low-voltage logic bidirectional conversion
2. One-way conversion of 2 channels of high-voltage logic into low-voltage logic
3. The module is compatible with breadboards and can be directly plugged into the breadboard for use
4. Realize the direct 5V and 3.3V level communication of the serial port.
5. The highest stable communication baud rate is 28800bps.
6. It can realize the bidirectional conversion of 3V-5V level of UART, IIC, 1-wire, SPI and other bus signals.
7. Compatibility:
(1) AVCC connects to 5V system power supply (2) ASCL connects to 5V system SCL
(3) ASDA connects to 5V system SDA (4) AGND connects to 5V system GND
(5) BVCC connects to 3V system power supply (6) BSCL connects to 3V system SCL
(7) BSDA connects to 3V system SDA (8) BGND connects to 3V system GND
Application range:
1. Serial communication between 5V single-chip microcomputer and 3.3V single-chip microcomputer.
2. The 3.3V serial downloader communicates with the 5V MCU serial port.
3. Serial communication between 5V MCU and 3.3V application module.
Instructions for use:
Wiring instructions:
HV connects to 5V power supply
LV connects to 3.3V power supply
GND is connected to the negative pole of the power supply, and the two power supply common grounds
RXI inputs 5v TTL, and RXO outputs 3.3v TTL
TXI input and output 3.3V TTL, TXO input and output 5V TTL, TXI and TXO two-way conversion
