Voltage converters

Logic level converter is a 4-channel bidirectional module that enables safe connection of devices operating at different voltages, such as 1.8 V, 2.8 V, 3.3 V, and 5 V. It provides smooth communication between Arduino microcontrollers powered at 5 V and ESP8266, ESP32, or Raspberry Pi circuits. Compact dimensions and 12 pins simplify mounting. The module effectively protects components from damage caused by excessive voltage, ensuring reliable logic signal translation.

Voltage-to-PWM converter is a universal module that converts 0-5V or 0-10V signals to PWM 0-100%. Input range selection is via a convenient jumper. The device is ideal for smooth control of DC motors, fans, and pumps. The module is fully compatible with popular microcontrollers such as Arduino, ESP32, and Raspberry Pi. The integrated potentiometer enables precise calibration, and compact dimensions simplify mounting in automation systems and electronics projects.
