OSEPP? Mega 2560 R3 Plus
The OSEPP? Mega 2560 R3 Plus is the bigger brother to the OSEPP? Uno board with more flash memory more SRAM more EEPROM and more pins. This board is perfect for projects that require a lot of inputs/outputs or that require more complex programs that cannot fit into the smaller memory of the ATmega328P.
New in R3:
Added SCL/SDA pins next to AREF header
Added IOREF pin to power header
?Plus? Features:
Replaced USBB connector with more popular miniUSB connector
Added Molex connector for easy connect to OSEPP? sensors and other I2C devices.
Specifications:
Microcontroller ATmega2560
Clock Speed 16 MHz
Flash Memory 256 KB
SRAM 8 KB
EEPROM 4 KB
Operating Voltage 5 V
Input Voltage 612 V
Digital I/O Pin Count 54 (including 14 for PWM output)
Analog Input Pin Count 16
Other Connections MiniUSB
ICSP for ATmega2560
DC power connector
4pin latchable Molex connector
Dimensions 4.23 x 2.13 x 0.61 inches (107.5 x 54.0 x 15.5 mm)
Power Source USB or external DC power supply
Highlights:
8bit AVR RISCbased microcontroller running at 16 MHz
8x more flash and 4x more SRAM and EEPROM than the Uno
Connects to a computer via a standard USB cable
Flexible power source (USB or DC power)
ICSP header for programming microcontroller
Compatible with existing Arduino software libraries
Compatible with the Ethernet and Motor Controller Shields
Features:
The ATmega2560 comes with the Arduino bootloader preloaded. There is an ICSP (InCircuit Serial Programming) header for the ATmega2560 to optionally replace the bootloader.
As an added precaution the board comes with a resettable polyfuse on the USB connection path. To prevent damage to the computer?s USB port the fuse will trip when the current to the port exceeds 500 mA.
The input and/or output pins are brought out to headers which enable a convenient way to prototype projects without the need of soldering or desoldering.
