Frequently asked questions
Does the Arduino-compatible board include a USB cable?
The board is listed without a USB cable, so you will need a USB cable to connect it to a computer for programming.
How do I wire the LCD1602 with the I2C adapter?
Connect the adapter's VCC and GND to 5V and GND, and connect SDA and SCL to A4 and A5 on an Uno-compatible board. The I2C address is commonly 0x27 or 0x3F, so check your module if the display stays blank.
