Please verify the board and accessories you received according to the accessory list provided in Appearance and Accessories and your optional configuration.
Before taking the board out of the package and powering it on for the first time, please be sure to perform the following inspections to prevent accidents after power-on.
Please follow ESD protection measures. Static electricity may damage the board!
The board does not have waterproof, dustproof, ESD protection, high-temperature resistance, and other configurations in the default factory configuration. Please ensure that your use environment is clean and free of abnormal factors such as condensation, frost, dust, static electricity, or high temperature.
After ensuring that all the above operations or inspections are completed, please follow the steps below for the first power-on.
If the serial port output information is consistent with the figure below, it indicates that the board initialization is normal.
Each board is written with factory test firmware when shipped from the factory. The firmware covers test programs for various modules of the board. You can overwrite it with your own firmware later, or you can re-download and program the factory firmware at any time through the Resource Summary page.
Please store the board properly when it is not in use to prevent the board from being damaged in harsh environments.
Please wrap the board with an anti-static bag and place the board in a place without heavy objects or sharp items to prevent crushing or piercing the board.
When transporting the board, please wrap the board with foam or similar padding, and avoid heavy objects pressing on the board during transportation, and avoid the board falling from a height.
