Description
Detailed Description:
The HKD 4-Channel Logic Level Converter is a simple and reliable module for safely interfacing devices operating at different voltage levels. It allows bi-directional signal conversion between 5V and 3.3V systems, making it ideal for I C, UART, SPI, and 1-Wire communication.
Compact and easy to use, the module requires connection to both high-voltage (HV) and low-voltage (LV) supplies along with a common ground. It ensures stable communication and protects low-voltage devices from damage when working with 5V logic systems.
This converter is perfect for microcontroller projects involving Arduino, ESP8266/ESP32, Raspberry Pi, and other 3.3V/5V platforms.
Features:
- 4-channel bi-directional logic level shifting
- Supports 5V 3.3V system compatibility
- Works with UART, I C, SPI, and 1-Wire protocols
- Simple 4-pin connection for HV, LV, and GND
- Power input includes anti-reverse protection
- Stable communication up to 28800 bps
Specifications:
- Channels: 4 bi-directional
- Input Voltage (HV): 5V system
- Input Voltage (LV): 3.3V system
- Current Output: 150mA
- Max Baud Rate: 28800 bps
- Dimensions: Compact PCB design
- Compatibility: Arduino, ESP, Raspberry Pi, microcontrollers
