Mega2560 Pro Mini
The Meduino Mega2560 Pro Mini R3 board is a smaller version of the Arduino Mega2560 R3. For some projects, when the Arduino Mega2560 is too big, then you can choose our Meduino Mega2560 Pro Mini board. It has a much smaller size, and also has all the IOs of Arduino Mega2560.
- Completely compatible with original Arduino Mega2560
- Pin pitch: 0.1 inch
- Size: 5.42cm*3.68cm
- With Atmega16U2 chip as the USB to Serial converter
- Working voltage: 5V
- Input Voltage: 7-12V
- Analog Input Pins: 16
- Digital I/O pins: 54
The following picture shows the pinouts of the board.
The Mega2560 Pro Mini board has all the IOs of Arduino Mega2560 R3, following are the parameters.
- Microcontroller ATmega2560
- Operating Voltage 5V
- Input Voltage (recommended) 7-12V
- Input Voltage (limits) 6-20V
- Digital I/O Pins 54 (of which 15 provide PWM output)
- Analog Input Pins 16
- DC Current per I/O Pin 40 mA
- DC Current for 3.3V Pin 50 mA
- Flash Memory 256 KB of which 8 KB used by bootloader
- SRAM 8 KB
- EEPROM 4 KB
- Clock Speed 16 MHz
The usage for the Mega2560 Pro Mini board basically is the same as Arduino Mega2560(just this board has a small size and different pinout). The Mega2560 Pro Mini can be powered via the USB connection or with an external power supply. The power source is selected automatically. We suggest using 7V-12V external power supply. The power pins are as follows:
- VIN. The input voltage to the Mega2560 Pro Mini board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin.
- 5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board.
- 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 150 mA.
- GND. Ground pins.
