If I have ATSAMR21-XPRO (Arm)
can I plugin / attach such a smaller board without USB like ATRCB256RFR2-XPRO and program it with Atmel Studio?
I know other boards I can open some SWD Jumpers and attach another boards SWD 6 Pin connector not having USB-Debugging itself.
I need 2 boards for testing radio, can second one be a smaller one programmed with first?
If, can second one be a Atmega and programmed by first being an Arm, or have both to be Arm then?
Or do I need 2 boards with full usb debugging anyway, or in case I have one Arm and one Atmega?
Thank You Breadboard
