Hello,
I've a question: Can I power the SparkFun SAMD21 Dev Breakout directly in 3.3v pin? My project have a gsm module with 2A peaks and I will power al with a 3.3 2A dc-dc converter powered by a SparkFun Battery Babysitter.
I think all would work fine with the dc-dc regulator but I don't know if it's a good idea power directly the SAMD21 with 3.3V or I need to modify something (like unsolder the APK2112K-3.3V, cut some trace or something similar)
Best regards.
