Plastic&Metal 4 channel Pin Header Blue/Green Bi-Directional Module for IIC UART SPI

Label:Yes The level conversion module is not a power conversion module!! Quantity:1pc Brand new with high quality Color:Blue Green Material:Plastic&Metal for IIC UART SPI It must be connected to a 5V power supply to work properly!

Product Features: 1. The four MOSFETs achieve bidirectional conversion between four channels of 3V and 5V levels, 2. The power input features reverse polarity protection, integrates a 3.3V LDO, and can provide an external current not exceeding 150mA 3. Equipped with a power indicator light, it's easy to see whether it's working or not 4. It can achieve bidirectional conversion of bus signals such as UART, IIC, 1-wire, SPI, etc., with voltage levels ranging from 3V to 5V Product Overview: Because part of the single chip microcomputer development board and equipment is 3. 3V work, and there is a single chip microcomputer development board and equipment. sensors and so on is 5. 0V power supply. so when the two need to communicate. there is a working voltage inconsistency. so that the user is not convenient to use. This product is designed for this problem and to solve this problem. This module provides the possibility of bridging different devices at 3. 3V and 5. 0V Features: 1. 4 channels of high voltage logic and low voltage logic two-way conversion 2. 4 channels of high voltage logic into low voltage logic one-way conversion 3. The module is compatible with the breadboard and can be directly inserted into the breadboard 4, to achieve direct 5V and 3. 3V level communication of serial port 5. the highest stable communication baud rate 28800bps 6. can achieve UART, IIC, 1-wire, SPI and other bus signal 3V-5V level two-way conversion. 7. Compatibility: (1)AVCC connected to 5V system power supply (2)ASCL connected to 5V system SCL (3)the SDA ASDA connect 5 v system (4)the AGND GND 5 v systems (5)BVCC connected to 3V system power supply (6)BSCL connected to 3V system SCL (7)BSDA connects to the 3V system. SDA (8)BGND Connects to the 3V system Scope of appl ication: 1. 5V microcontrol ler and 3. 3V microcontrol ler serial communication. 2. 3. 3V ser ial port download communicates with 5V microcontrol ler serial port 3. The 5V single-chip microcomputer communicates with the 3. 3V application module ser ial port. Wiring instructions: LV(1-4) 1/0 3. 3V TTL. HV (1-4) 1/0 5V TTL. LV(1-4) and HV(1-4) are mutual ly rotating Note: 1. If the power supply in the high voltage area and the low voltage area is already in common ground, G in this module only needs to be connected to one ground. 2. The conversion module is equivalent to a straight line, each port corresponds one by one, but the voltage of the two sides is different, thus realizing the communication between different levels. 3. This module can not be used as the function of voltage regulator or transformer. It can only be used for small current communication between 10 port levels. 4. This module has no welding. but it has matching. Package Include: 1pc 4 channel Pin Header IIC I2C Logic Level Converter Bi-Directional Module for 5V to 3.3V IIC UART SPI Notice: 1.Transition: 1cm(0.39in)=10mm=0.39inch. 2.Please allow 1-2mm(0.04-0.08in) error due to manual measurement and make sure you do not mind before ordering. 3.Please understand that colors may exist chromatic aberration as the different placement of pictures.
