Thanks! It looks like this design makes soldering pads easier than designs i saw before.
But I’m actually trying to avoid doing any soldering at home, so I’m looking for ways to set things up without soldering.
I’ll use non-rechargeable CR2032 battery, like example below. and i will remove it when I need to connect the board to a PC for flashing. So I don’t need to worry about charging.
Here’s one of the reference projects I found:
https://github.com/hazels-garage/bad-wings/tree/master/slim
In this project, the three pins on the XIAO BLE ( B-, GND, and GND pad ) are all connected together by the PCB.
My question is: are those pins internally connected on the XIAO BLE board without any electrical logic?
-
If they’re already connected inside the board, then I don’t see a reason to connect them again on the PCB.
-
But if they’re not connected internally, is it safe to connect them externally like that?
I’ve been trying to read through the XIAO BLE documentation and posts like this to find out, but I don’t really have much background in electronics, so I’m having a hard time understanding them.
