This Bi-Directional Logic Level Converter is a breadboard-friendly device that converts between eg. 5V and 3.3V logic. The four channels are independent and work in both directions, making this converter appropriate for shifting I2C bus voltages.
Power the board from the two voltage sources you're using. Connect the higher voltage (eg. 5V) to the 'HV' power pin, the lower voltage (eg. 3.3V) to the 'LV' power pin, and the ground to the 'GND' pin.
Features:
- 4 independent channels
- Breadboard friendly - just bring your own pin headers
- Small size (15x13mm)
- Manufactured and supported in Australia by Core Electronics
