Our new Opto-Isolator Mini Board is an easy to use, compact solution for converting from a 3V output signal to a standard 5V TTL output. Ideal for use with the new 3.3V Microcontrollers such as the MPS range and many others. Each output is opto-isolated for safe operation with your 3V microcontroller.

This unit includes 8 Opto-isolators to provide a standard port conversion between a 3V output port to a standard 5V output. High-quality, High-Voltage, fast conversion PC817 Opto-isolator is used on this board. Together with standard IDCC and male/female headers for easy connection to your control system or development board. The board can be mounted easily and includes mounting holes.

The Opto-Isolator Mini Board is a small compact solution to a problem that is becoming increasingly common with the new low power consumption 3V microcontrollers available on the market now.
