Part of a series of Arduino-compatible micro-controllers with the addition of the Mega Pro. This is a 3.3V microcontroller running a version of the stk500v2 bootloader at 8MHz. Just like the other Pro-series boards this board is built with all SMD components and comes with no headers populated in order to minimize the cost and the board profile. Of course this board has the same pin-configuration as the Arduino Mega so it is dimensionally shield compatible (but do keep in mind that this is a 3.3V board unlike the Arduino Mega).
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 and the DC power jack footprint is available, but not populated.
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.
- 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
- DC input 3.3V up to 12V
- Resettable fuse prevents damage to board in case of short
- Power select switch acts as on/off switch
Available in the UK from SK Pang.
