Sea-Picro

Sea-Picro is a RP2040 based board in the Arduino Pro Micro form factor. Like Sea-Micro, it's designed to be a drop in replacement for keyboards wanting an upgrade from ATmega32u4 based pro micros.

Features

• Compatiable with most pro micro based keyboards
• RP2040 microcontroller, with dual M0+ processors at up to 133MHz
• Mid mount USB-C connector, which is low profile and can't be ripped off
• Optional Elite-C style pinout, adding an additional 5 IO for large keyboards
• Single button reset / bootloader circuit which changes behavior based on how long it's held (RP2040 usually requires two buttons to flash new firmware, making it challenging when installed upside down in a keyboard)
• ROM bootloader which prevents board from being bricked
• Onboard power LED.
• IO pinout identical to the Sparkfun RP2040 Pro Micro
