Special Features

  • Package Contents:Includes 10 sets of 4-Channel Bi-directional Logic Level Converter Modules. Each module comes with one male-to-female and one female-to-female jumper wire for immediate plug-and-play use. Featuring an onboard SMD chip design, the ultra-small size of approximately 15×13mm makes integration easy. Standard pin pitch ensures perfect compatibility with breadboards, making it an ideal choice for prototyping and embedded projects.
  • Product Features:Specifically engineered to resolve communication issues between devices operating at different voltages (e.g., 5V and 3.3V). Supports 4 channels of bi-directional conversion between high and low voltage logic, as well as high-to-low unidirectional conversion. It safely steps down 5V signals to 3.3V and boosts 3.3V signals to 5V. It is also compatible with even lower logic levels, such as 2.8V and 1.8V. Data is seamlessly and transparently transmitted by connecting the high and low-voltage side pins, ensuring perfect signal matching.
  • Compatibility:Utilizes a bi-directional FET Open-Drain design, offering broad compatibility with common digital protocols including UART (Serial), I2C, SPI, and 1-Wire. Supports TTL serial and low-speed SPI ($leq 2 ext{MHz}$) data transmission, with a maximum stable communication baud rate of 28800bps. The module can directly facilitate 5V and 3.3V serial communication, ensuring reliable signal interaction across various interfaces.
  • Easy Installation:The module features clear markings for "HV" (High Voltage side), "LV" (Low Voltage side), and "GND". Simply connect the high voltage (e.g., 5V) to HV, the low voltage (e.g., 3.3V) to LV, and the common ground to GND for power. Each channel is independent and has a one-to-one correspondence, requiring no extra configuration. Detailed pin definitions (e.g., AVCC/ASCL/ASDA) ensure simple and straightforward wiring logic.
  • Wide Range of Applications:Widely used as a perfect communication bridge in microcontroller and embedded development for bus debugging, voltage isolation, and data acquisition. Typical scenarios include serial communication between 5V and 3.3V microcontrollers, interfacing a serial programmer with a microcontroller, and safely connecting 3.3V sensors, display modules, and wireless units to a 5V main control board.
