Reset Pin

 I am about to build my LoPy (including expansion board) into a case. I want to add an external reset button. Do I wire a switch directly between GND and the reset pin RST? I think this is Pin 9 on the mainboard.

 @rvandam, it already has it's own internally, so you don't need to add one.

 @abilio No pull up resistor? Or is there already an internal one.

 @pheaton, yes, reset button on the LoPy is wired the same :)
