Feature
The power supply voltage is DC 5V.
The installation of SMD LED and SMD electrolytic capacitor should pay attention to the positive and negative electrodes. The side with green mark on the SMD LED is the negative electrode, and the solid semicircular side of the electrolytic capacitor is the negative electrode.
When installing the SCM, you must confirm the first foot. Install the MCU one foot in the direction of the flat angle on the installation position of the SCM on the circuit board. The microcontroller will not work if installed incorrectly. When soldering the SCM, the USB socket is installed on the same side as the SMD component (the side with the word), and cannot be installed on the back (no word side). If it is installed incorrectly, the positive and negative poles of the power supply will be reversed, which will damage the MCU. J2 To choose the power supply mode (USB power supply or external power supply), use a short-circuit cap to choose. When using an external power supply, pay attention to the positive and negative power supply and voltage.
