Do you need "Mega" power in a "Mini" package? We can do that! We're continuing our Pro series of Arduino-compatible microcontrollers with the addition of the Mega Pro Mini. This is a 3.3V microcontroller running a version of the stk500v2 bootloader at 8MHz. In order to shrink the Mega Pro down to its minimum footprint, we've condensed the board layout, removed the barrel jack footprint and replaced the traditional Arduino-style headers with compact vertical JST connectors.
