The first is device selection. In the preparatory stage of the project, device selection is an important work content. Correspondingly, the datasheet of each chip will have an introduction and feature list at the beginning of the most eye-catching position, including the power supply voltage, current, power consumption, resources, package information and other basic contents of the device. Through these contents, we can quickly identify the chip. Functions and areas of use, in order to quickly screen, complete the selection work, and determine whether the chip can meet the project requirements.

After determining the device model, we will start the subsequent hardware design work. For hardware engineers, device packaging, pin assignments, pin diagrams and functions, and reference designs are the primary concerns. With these parts in place, the hardware engineer can start working right away.

After completing the preliminary PCB structure design, in the common parts, such as power supply, reset, debugging circuit, etc., we can try to refer to these useful documents, read the layout design guide in detail, reduce the risk in PCB layout and wiring, and improve the probability of success. After confirming that the schematic diagram is correct, we start the layout and routing of the PCB. Some datasheets will considerately include the PCB layout of the reference board, and some will form a separate demo document for this part of the content.
