Hello.
I've been experimenting with AVR alot for 2 years. But I also got a bit of taste ARM, but not alot.
What board should I start for developing? I want a cheap and a small one. Also I don't want one that needs a programmer like avr's do.
Thanks for the help!
If you are familiar with Atmel Studio (their free software development tool) you can use it for any of the AVR or Cortex board that Atmel make.
For AVR a good one to use is the ATMEGA328PB-XMINI board.
For Cortex M, a good starting point is the ATSAMD21-XPRO board.
Programming/Debug is via a simple USB cable form your PC.
Extension boards are also available.
If you are using the Arduino environment then there is also an "Arduino Zero" board that uses the SAMD21 Cortex M0+
Good luck.
The suggested retail price for SAM D21 Xplained Pro is (USD) $30.6 and Arduino/Genuino ZERO is priced at €42.90 / (USD) $48.57. These boards might have features that justify the higher prices.
