I would like to have a ‘reset button’ using the pogo pad on the underside of the Xiao (near the SWDIO/SWCLK pads).
What should I include to achieve that?
Is there anything else needed other than a tactile switch pulling that pin to ground?
Can it be any ground (i.e. the pin between 3.3v and 5v), or does it have to be to the ground pad next to it?
Do I need any resistors or capacitors to protect that pad?
I tried looking at the schematics, but I could only find one reset pad (TP2), and I wasn’t sure if that was the reset pad on the top or the one on the underside of the board?
