D&V Engineering

1. Input Voltage: 6.5-12 V (DC) or USB power supply
2. Output Voltage: 3.3V or 5V can switch over
3. Maximum Output Current: <700 ma
4. Fluctuation two road independent control, can switch over to 0 V, 3.3 V, 5 V
5. On-board two groups of 3.3V, 5V DC output plug pin, convenient external lead use

1. Use this power regulation module to provide 5V and 3V3 power supply to your breadboard based project.This power supply board is designed to plug into a Breadboard panel with 2 power Distribution strips. The module can be powered by a USB port or an external power supply 7-12V. The module has two independent power lines, which can be set to output voltage of 5V or 3.3V, or completely remove power from the line. The module has ON / OFF switch to turn on and off module. It comes with reverse polarity and short circuit protections, which greatly helps during building and testing circuits on the breadboard.
