= Important Notes =

No short circuit protection is included on this module

For short circuit protection, connect a self-recovery fuse in series at the input

Do not exceed 5V input voltage

Ensure correct polarity when connecting power

This is a boostonly module output voltage is always higher than input

For critical applications, add output capacitor for cleaner 5V supply
