The entire board uses 0402 package resistors and capacitors. It is recommended to use solder paste and a soldering station for easier operation. After
the software
board is soldered, it cannot be used directly. You need to program the Atmel microcontroller with the Arduino bootloader before you can use the serial port for programming.
For detailed steps, please refer to the following: After burning
