Voltage converters

The voltage-to-PWM converter is a universal module that converts a 0–5 V or 0–10 V signal into a 0–100% PWM signal. The input range is selected using a convenient jumper. The device is ideal for smoothly controlling DC motors, fans, and pumps. The module is fully compatible with popular microcontrollers such as Arduino, ESP32, and Raspberry Pi. The integrated potentiometer allows for precise calibration, and its compact dimensions make it easy to install in automation systems and electronics projects.

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.

The 8-channel logic level converter TXS0108E enables safe communication between devices with different voltage standards. It supports 1.2V - 3.6V and 1.8V - 5.5V ranges and works well with Arduino, ESP32, and Raspberry Pi systems.

The module offers automatic direction detection, throughput up to 110 Mbps, and compatibility with I2C, SPI, and UART. It is essential when connecting sensors, displays, and wireless modules that run at different supply voltages.
