• Do not exceed the specified operating voltage (4.75V-12V DC input), as this can damage the module.
• Exceeding the maximum allowable power consumption will result in excessive chip temperature, potentially leading to damage or reduced lifespan.
• Ensure correct polarity when connecting the input power. Reversing polarity will result in a short circuit and damage the module.
• Handle the module with care to avoid electrostatic discharge (ESD) damage.

5. Eto ati Asopọ

The AMS1117-3.3 module features three main pins for connection: VIN (Input Voltage), GND (Ground), and OUT (Output Voltage). Refer to the connection diagram below for proper wiring.

1. Input Connection (VIN): Connect the positive terminal of your DC power source (4.75V-12V) to the 'VIN' pin on the module.
2. Isopọ ilẹ (GND): Connect the negative terminal of your DC power source to the 'GND' pin. Ensure this is a common ground for both input and output.
3. Output Connection (OUT): The regulated 3.3V DC output will be available between the 'OUT' pin (positive) and the 'GND' pin (negative). Connect your 3.3V load to these pins.
4. Ìmúdájú: Before connecting sensitive components, it is recommended to verify the output voltage using a multimeter to ensure it is stable at 3.3V.
