SeeedStudio Xiao

SeedStudio XIAO

SeeedStudio Xiao

It been a while since I last did any review on new mico-controller boards but this cute little board is small yet powerful. In the past, I have used Arduino Zero boards before with the SAMD21 Cortex M0+ but they comes usually pretty large form factor. This product from SeeedStudio called Xiao.

Let's run through the pinout of this tiny fellow. It comes with 11 Digital pins ( D0 to D10 ) which also double as Analog pind ( D0 to D10). Some of the pin also double as other functions like Serial ( D6 - Tx, D7 - Rx ), I2C ( D4 & D5 ) and SPI ( D8, D9, D10 ) so it should satisfied most of the basic needs of an Arduino board.

Besides being small, the price is also small at US$4.90 and comes with USB-C. I really like USB-C compared to the Micro-USB that gets yank off easily.

As I have a little bit time due to the lockdown here in Malaysia and I have designed some 90 degree WS2812 PCB Adapters from SeeedStudio Fusion, I decided to make a LED project.

With four LED adapter, you can make a nice looking square LED shape. For a size comparison, the SeeedStudio Xiao is even smaller than the 90 degree LED adapter!!!!

As I do not usually use breadboard that often, I decided to solder the male header pins facing the top instead.

Everything wired together and connect to the 5V power supply. Below are some video from the projects.
