Enhanced Connectivity for Car Gauges and Automotive Tools & Equipment

Unlock the potential of your car gauges and automotive tools & equipment with the Songhe 4 Channels IIC I2C Logic Level Converter Bi-Directional Module. Designed for seamless integration, this versatile module allows you to connect devices operating at different voltage levels, enabling smooth communication and expanded functionality.

Effortless Compatibility and User-Friendly Design

Engineered with simplicity in mind, the Songhe Logic Level Converter is exceptionally easy to use. By connecting the module to two voltage sources - one for high voltage and the other for low voltage - you can effortlessly bridge the gap between incompatible devices. This eliminates the need for complex wiring and reduces the risk of damage to your valuable equipment.

Expanded Possibilities and Versatile Applications

With the Songhe 4 Channels IIC I2C Logic Level Converter, the possibilities for application are vast. Here are some areas where this product can make a significant impact:

  • Car diagnostic tools: Seamlessly integrate your diagnostic tools with different voltage requirements, ensuring accurate readings and efficient troubleshooting.
  • Automotive control systems: Connect various control modules and sensors within your vehicle, enhancing communication and enabling advanced functionalities.
  • Workshop equipment: Integrate different tools and devices in your garage or shop, such as oscilloscopes, multimeters, or data loggers, to streamline operations and expand your capabilities.
  • Embedded systems: Facilitate communication between microcontrollers and peripherals, allowing for robust and reliable data exchange in projects like robotics or home automation.

    • Experience the enhanced connectivity and flexibility provided by the Songhe 4 Channels IIC I2C Logic Level Converter Bi-Directional Module. Say goodbye to compatibility issues and unlock the full potential of your car gauges and automotive tools & equipment!

    The level converter is very easy to use, it needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. Take the high voltage (5V) and low voltage (3,3V) for example. 5V connects to HV pin;3.3V connects to LV pin;Ground from the system connects to GND pin. Green Board Not Blue.

    Works as expected.: Power Supply Accessory

    So far I have used this converter to convert 3.3V logic level to 5V logic level between ESP32 and stepper motor driver. The converter worked as expected.

    Pros
    • Great for me
    Cons
    • Appearance

    Simple level shifters that just work

    I have a Mr. Cool on board with TTL 5V serial communication. One of these level switches combined with an equally cheap Wemos D1 mini (which has a 3.3V serial port and a 5V to 3.3V DC adapter) quickly completed the project, and now I have full control over the air conditioning through my home automation.

    Pros
    • Nice packaging
    Cons
    • Thin

    I don't think they work

    Maybe I don't know what I'm doing but they don't work as I expected. Below is how I connect it and then restore. CONNECTED 3.3V to LV 5V to HV Ground both sides to ground All other pins open RESULT SL1,L2,L3,L4 all have 3.3V even with nothing connected! H1, H2, H3, H4 are all 5V, although none of the pins on the bottom are high. If I apply a 3.3V signal to one of the LV pins and connect the HV to my device, the HV pin drops to 3.3V.

    Pros
    • Few competitors
    Cons
    • There are errors

    Works like a clock for power converters

    There are no questions from the first connection. Not much to talk about - make sure you connect the HV, LV and GND pins and the signals are bouncing up and down (3v3 <-> 5v) without error. The circuit boards are clean and have easy-to-read labels. I used the first one to switch control signals from ESP8266 (3v3) to WS2812b (5v). This design is good when you don't need to enable/disable a switch in software (e.g. delay its arrival). online until the microcontroller boots up) becauseโ€ฆ

    Pros
    • A lot of positive emotions
    Cons
    • Communication with the seller

    Inverts the signal and has no documents - can be improved

    But without documents I assumed the connection of the HV 5.5 side, in my case it is due to the HV on the VG Ground the ground 5.5V .LV to my 3.3 and LG to 3.3 ground. NOW THE PROBLEM. Apply 5V to the Hx input, you will get 0 to the Lx output. UPDATE - October 23rd, 2020 I found an old data sheet from Phillips detailing what they do. They expect the signals to be pulled up. I suppose this would be fine for an I2C bus application. Useless to me. So I thought you might know that I connected theโ€ฆ

    Pros
    • Good product for its price
    Cons
    • Difficult to say

    They're simple and just work

    So far I've used bilevel converters in projects with no problems (except when prototyping too much signal noise on the breadboard). I have successfully connected the Raspberry Pi's 3.3V pins to a retro 8-bit 5V serial port for bi-directional communication (like file transfer). The photo uploaded shows three such devices, one still in an anti-static bag, another wire wrapped and still in the testing/development phase before installing it on a new breadboard, and a third between two coins on aโ€ฆ

    Pros
    • Quality construction
    Cons
    • Requires socket
