the component on the black drone frame. If you want to connect the power supply parts to the power supply, pay attention to the following points. If you want to quickly connect the connector and power supply parts to the power supply, be careful about short circuits. You can remove the other end of the power supply module and then weld the battery and connector, In this way, we can easily disconnect the drone battery and power supply components. Finally, the battery and power supply components

Requirement Without a network, a keyboard, or a monitor, controlling Raspberry Pi becomes a problem. I accidentally saw an article today.ArticleThat is, you can directly control the Raspberry Pi through the serial port. Give a decisive try. The effect is good. Share it with others!Pai_^ Preparation
