These days, Makers have access to quite a few different microprocessors for use in their projects. Most of them can be found on development boards of some sort, but not all are in a convenient size. The reason for this is that most of these development boards were designed with a breadboard in mind, and then after your prototype is done, you are required to design a PCB and place the specific processor and its supporting components onto this custom PCB…<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Many makers choose to skip this step, either choosing to keep the project on the breadboard, or place the entire development module onto a piece of stripboard or similar, and then place their supporting components and sensors around that.<\/p>\n\n\n\n

This is where the SEEED XIAO<\/a> is different. It comes in a thumb-nail-sized package and can be used on the breadboard or directly placed onto a PCB via either pin headers or if you want access to all of its features, SMD pads.<\/p>\n\n\n\n

SEEED XIAO SAMD21<\/figcaption><\/figure>\n\n\n\n

In this build, I decided to design a generic carrier board, that will accept most of the XIAO RP2040 or the XIAO SAMD21<\/a> <\/p>\n\n\n\n

I have also included a small prototype area on the PCB, so that Makers can easily transfer their existing XIAO projects onto a semi-custom PCB, without having to design their own.

I have also addressed a problem area, especially with the XIAO SAMD21, it has no onboard reset button, only two tiny pads, by including a reset button for ease of use.<\/p>\n\n\n\n

The PCB is in Arduino Uno form factor, and also provides headers to power it from an external 5v DC supply. Please note that the prototyping area has a 3.3v power rail, – due to the fact that all of the XIAO GPIO are limited to 3.3v anyway -. This power rail is powered directly from the XIAO 3.3v output, and the current is limited as per the specifications of the XIAO module that you are using.<\/p>\n\n\n\n
