Elite-C v4 ATmega32U4 Microcontroller

Differences to the Pro Micro

Changes

• 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.

Additions

• 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.
• There is now an additional VBUS pin above pin B0, allowing for easier connection of external USB ports.
• A physical reset button.

Omissions

• No indicator LEDs. The pins are instead available.
• It has no voltage regulator and runs only on +5V.
