OSEPP™ Pro Mini


Bookmark and Share
This is a miniaturized version of the Pro, so it's small enough to conceal in other projects. The Pro Mini is as small as it gets. Built on the 'open-source electronics prototyping platform', and compatible with existing Arduino software libraries.

• 8-bit AVR RISC-based microcontroller running at 16 MHz
• Extremely small profile – less than 1/5 the size of the OSEPP Pro board
