@33MHz yes 😊 It's my first PCB so nothing special, but fortunately my girfriend gave me the cool idea to use some of that surface area and microcontroller pins for LEDs and buttons :D 👍
@unixb0y I love the Feather form factor because they are breadboard friendly if you add the stacking headers. I think they have as much I/O as an Arduino, plus some additional nice tricks.
@33MHz The whole device is pretty cool though imho :) I'll write a more comprehensive blog article about it. It will help you to develop or learn about RF systems and was very helpful for a uni project of mine 👍
