Important Notes

Maximum output current: 500mA - do not exceed
Input voltage must be lower than output voltage (boost only)
For best efficiency, keep input voltage as high as possible
Do not apply input voltage above 3.3V
Module is a boost converter - output voltage is always higher than input
For higher current, choose a module with higher output rating

Safety Precautions

Do not exceed 3.3V input voltage
Ensure correct polarity when connecting power
Do not short output terminals
Keep away from moisture and heat sources
Verify load current before application
Allow adequate airflow for cooling
For continuous high-current operation, add a heatsink
