Adafruit has a good track record for introducing controller form factors that are popular.
The Arduino Zero is a collaboration of Atmel and Arduino. But nothing that has come out to date has said "we introduced this specifically targeting the customers for ______". There is some market-speak for Internet of Things and wearable usage. Who is going to put an Arduino Zero board in a wearable? If it costs $5 then people will try but this thing is shaping up to be big and probably at a price point that hurts.
So I open it up: if you had your choice of a perfect microcontroller board, what would you like to see?
- Large, small, "medium", compact, cubist, "fits in a ___"?
- Lots of input/output pins? Just enough?
- BIG ONE: 5 volt pins or 3.3 volt pins? (or 3 volt, 5 volt tolerant!)? Current per pin (Zero's 7 milliamps, Uno's 40 milliamps, or other)?
- Interfaces (serial, I2C, SPI, CAN, Ethernet, debug, USB)?
- Power? Solar, LiPo/battery, 5 volt, 3.3 volt?
- Bare metal real-time software (Uno etc.) or Linux, both, other?
- Other features?
In a following post I'll compile a user-desired board and my next dream board.
