OVERVIEW his 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. HIGHLIGHTS • 8-bit AVR RISC-based microcontroller running at 16 MHz • Extremely small profile – less than 1/5 the size of the OSEPP Pro board This board is based on the Arduino Pro Mini designed by SparkFun Electronics, and is released under the Creative Commons Attribution Share-Alike License.
