10pcs 2/4 Channels IIC I2C Logic Level Converter Bi-Directional Module 3.3V to 5V Shifter for

2 way level conversion module 3.3V/5V IIC UART SPI

Ts:

Product Features:

Because some MCU development boards and devices work at 3.3V, and there are MCU development boards, equment, rs, 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 addre and soe this problem. This module provides feasibility in different devices of 3.3V and 5.0V, and acts as a bridge.

Product parameters:

1. Two-channel high-voltage logic and low-voltage logic bidirectional conversion

2. The module is compatible with breadboards and can be directly plugged into the breadboard for use

3. Stable communication baud rate within 28800bp

Product application range:

1. Serial communication between 5V single-ch microcomputer and 3.3V single-ch 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.

4. Realize the direct 5V and 3.3V level communication of the serial port.

5. It can realize the bidirectional conversion of 3V-5V level of UART, IIC, 1-wire, SPI and other bus signals.

Instructions for use:

HV is connected to 5V power supply, is connected to 3.3V power supply, GND is connected to negative power supply, two power supply common grounds, RXI input 5V TTL, will output 3.3V TTL at RXO, TXI input and output 3.3V TTL, TXO input and output 5V TTL, TXI and TXO two-way conversion. For example, the two syst of 5V system A and 3.3V system B carry out IIC communication, and the wiring method is as follows:

(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

Notice:

1. If the power supply in the high-voltage area and the low-voltage area have a common ground, the GND in this module only needs to be connected to one ground.

2. The conversion module is equivalent to a straight line, and each port has a one-to-one correspondence, but the voltages on both sides are different.

So as to realize the communication between different levels.

3. This module cannot be used as a voltage stabilizer or . It can only be used for small current communication between IO port levels.

4. There is no welding on the pin header of this module, but it is matched.

4-channel level conversion module 3.3V/5V IIC UART SPI

This product is a level conversion module, not a power conversion module! ! Must be connected to a 5V power supply to work normally! Don't buy if you don't know!

Product Features: 1. The four MOS tubes realize the two-way conversion of four 3V and 5V levels, 2. The power input has anti-reverse connection protection, integrated 3.3VLDO, and can provide an external current of no more than 150mA 3. With power indicator, it is clear whether it is working or not at a glance 4. It can realize the bidirectional conversion of 3V-5V level of UART, IIC, 1-wire, SPI and other bus signals Buy this product to get: One module that has been welded and tested
