Description: 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.

The Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off board. This board connects directly to the FTDI Basic Breakout board and supports auto-reset.

Note: Because modifications were made to the bootloader to support the 3.3V system, you will need to download and install a new board definition so that the Mega Pro can be programmed in the Arduino environment. The .zip archive below contains all of the files that you'll need including a "readme" file with simple instructions for how to install them.

Features:

• ATmega2560 running at 8MHz external resonator
• Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, Accelerometers, sensors, etc)
• USB connection off board
• 3.3V regulator
• Over current protected
• Reverse polarity protected
• Resettable fuse prevents damage to board in case of short
