Pro micro and their clones and compatibles have been the goto standard for the hobby's kit boards for a while. Then came the Elite-C.
The latest version from Maple Computing is available and shipping at RingerKeys!
v4 brings us:
- proper use of external USB ports by VBUS pin added above pin B0
- an even lower profile reset button
- USB-C port, mid-mounted, is now the limiting factor to thinness of the board.
always had vs Pro-Micro:
- The USB port is now USB type C mid-mount, which is both through-hole and SMD mounted. It should be tougher and not as easily torn off as the USB micro B port on the original Pro Micro
- The RAW pin on the Pro Micro has been replaced with PB0.
- The bootloader is DFU.
- The silk-screened print on the board lists the actual ATmega32U4 port and bit numbers, not Arduino numbering.
- Five additional I/O pins are exposed on the short edge. (PBO replaces the old RAW pin, for a total of six new I/O pins, making the total 24 out of the ATmega32U4's 26)
- There are also holes for the USB port, for an external USB breakout board.
- A physical reset button.
- It has no voltage regulator and runs only on +5V.
