The previous section describes how to write a Raspberry Pi system to the Raspberry Pi, and today we'll show you how to configure the Raspberry Pi for better use.If you have a monitor. Keyboard mouse, direct start can go to the des

, please plug in the brush board, using the accompanying checkchipversion. WIN7/8 PL2303 users can directly plug in the brush board, the system will automatically download the driver (of course, to network). However, after plugging in the machine board, you will see the normal running COM device in Device Manager before you can proceed to the next step.Then make some settings:Set the baud rate of the brush board to 115200 (because the Raspberry

The answer is yes. There are 26 pins on the Raspberry Pi Board, these gpio (general purpose I/O) including SPI, I²c, serial UART, 3V3 and 5V power supply.
