Background<\/h2>\n\n\n\n

When you buy a Raspberry Pi<\/a> for the very first time and want to configure it, the most common method would be to connect a keyboard, mouse, and display to the Raspberry Pi. But this can be a very troublesome option since you might have to carry them with you when you are traveling. <\/p>\n\n\n\n

So, the alternative option which makes it a more simple process is by using a USB to Serial adapter to establish a connection between the Raspberry Pi and your computer. <\/p>\n\n\n\n

What if there is a new method to connect to your Raspberry Pi?<\/strong><\/h2>\n\n\n\n

Using Seeeduino XIAO is the way to go. But one might think it is an Arduino compatible development board and might be confused about how it can be used to connect to a Raspberry Pi.<\/p>\n\n\n\n

Seeeduino XIAO will allow you to connect to your Raspberry Pi through a serial connection and establish this connection just by using Arduino IDE! Normally when you use a USB to Serial cable to connect with your Raspberry Pi, you need to install additional software drivers for that cable to work. But if you already own a Seeeduino XIAO and want to use it to configure your Raspberry Pi, it will be a very easy process. Also, when you are done using Seeeduino XIAO to communicate with your Raspberry Pi, you can continue to work on your other Arduino projects with the Seeeduino XIAO!<\/p>\n\n\n\n

What is Seeeduino XIAO? <\/strong><\/h2>\n\n\n\n

Seeeduino XIAO<\/a> is the smallest member of the Seeeduino family. It carries a powerful Arm\u00ae Cortex\u00ae-M0+(SAMD21G18) CPU which is a low-power Arduino microcontroller. On the other hand, this little board has good performance in processing with less power needed. As a matter of fact, it is designed in a tiny size and can be used for Arduino wearable devices and small projects.<\/p>\n\n\n\n

What is Serial Communication?<\/strong><\/h2>\n\n\n\n

Serial communication is a communication method used in telecommunications where data is transmitted one bit at a time in sequential order over a communication channel. It has different protocols such as CAN,\u00a0ETHERNET,\u00a0I2C,\u00a0SPI,\u00a0RS232,\u00a0USB,\u00a0UART, 1-Wire,\u00a0and\u00a0SATA.<\/p>\n\n\n\n

It is the simplest form of communication between a sender and a receiver and advantageous in long-haul communications.<\/p>\n\n\n\n
