LCD2004 display is a dot matrix module designed to display 20 characters including letters, numbers, and symbols, supporting 4-bit and 8-bit data transmission modes. It’s quite convenient for beginners to call the built-in library Liquid Crystal of Arduino IDE, no need to edit yourself.
Working voltage: 5V; Contrast adjustable with a 50K potentiometer onside. To use the 3.3V backlight, just connect pin A to 3.3V, pin K to GND.
NOTE: Please solder the pin headers on it before using.

6. Customs & Import fees
Such as the products you buy on our site - can't simply be shipped freely from country to country. When goods are imported into a different country or customs territory, there is a charge called Customs Duty that must apply. This is charged by the local customs authority where the goods are being imported into.
If Customs Duty is payable to your territory, you'll be responsible for paying it to the authorities, so SunFounder isn't involved in this process. Whether Customs Duty is payable, and by how much, depends on a whole lot of different things. For example, many countries have a 'low value threshold' below which they do not charge any Customs Duty.
If you do have to pay Customs Duty though, the amount payable is usually calculated based on the value of the goods and the type of goods being imported.
AND IF I DON'T PAY THE CUSTOMS DUTY?
If, for whatever reason, you refuse the customs fee and the parcel is returned back to us. If you're still unsure on whether you'll be subject to customs fees, we recommend contacting your local customs office for more info before placing your order!
