Hey buddy, thanks for the reply. I looked at your PCB link and very impressive, but ultimately, what does your device do?
I was originally concerned about being able to utilize the XIAO in a mass produced PCB because I couldn’t figure out a way to connect the BAT pads using conventional PCB fabrication options, but I found a great voltage regulator (MCP-1700) which works perfectly on the 3V3 pin. The built-in charger only runs at 100ma (to my understanding) so I am using an external battery charging module anyway (my battery is very large). I’d love to share my project with everyone, but I am still filing patents and stuff so it is still :X for now.
But back to my original question, I’d love to know of/see other commercial projects that use the XIAO. And also if there are any logistical issues I am overlooking. The XIAO could be a paradigm changer considering its cheap price!
