Arduino Mage2560 ATmega2560 upgrade an improved version Freaduino Mage2560

Freaduino Mage2560 is independently developed by the ENF e 100% compatible with an upgraded version of the official Arduino Mage2560 development board.Freaduino Mage2560 addition to the more than excellent Layout layout, but also more convenient in use. For example: Add the 3.3V and 5V power supply switching options, so you can use more support and direct such XBee, Bluetooth Bee, RF, and the like need to 3.3V operating mode of the module. For example, the Reset Button and then into the side of the button, so use the Shield will not appear when the expansion board can not be the case according to the Reset button.

These are Freaduino exquisite small intimate details of the design, more user-friendly design, we want users to use the process to appreciate our focus.



Arduino Mega is a piece of the ATmega2560 microcontroller as the core of the development board, with its own set of 54 digital I / O input / output terminal (14 of which group can do PWM output), more than 16 sets of analog inputs, 4 UART (hardware serial ports), using the 16 MHz crystal oscillator. As a bootloader, so the program can be downloaded directly via USB without the need for an external programmer through the other. Some choose to supply power directly from USB, or use the AC-to-DC adapter and battery as an external power supply.

Freaduino features:
Arduino's MEGA2560 with all the features.
The MEGA2560 Arduino compatible pin layout, screw hole and dimensions.
Selectable 3.3V or 5V operation
LED indicators more visible location
Wide range from 7 - 23V DC external input
More powerful current is guaranteed to support the ability to drive more modules
SMD components to upgrade more



Freaduino improvement:
1 Operating voltage 3.3V / 5V optional. Arduino can only work in 5V, 3.3V all levels often encountered in the interface module, IO ports can not be directly connected to the conversion level needs to be done - such as SD Card, Bluetooth module.Iteaduino toggle switch so that it can work at 3.3V, this time the IO port voltage is 3.3V and 3.3V can work with the module level. (Note: 3.3V 16M state of the MCU clock is overclocking, but after the actual test, MCU job stability, ease of use)

2 more power. Arduino using FT232RL 3.3V output supply, the maximum output current of less than 100mA, encountered peripheral modules require high current, it will have enough power. Freaduino use 1117-3.3 output 3.3V power supply, the maximum current of 800mA. Arduino's 5V supply only 500mA, LDO and Freaduino change the original design DCDC, can provide up to 2A of 5V power supply.

3 more visible LED. When the lights Arduino board expansion will be blocked plug, can not see the PWR, TX and RX indicators. Freaduino the edge of the light moved to the board, even if there are expansion boards can also see the light.

4 is easier to press the reset button. Arduino reset button in the expansion board inserted will be blocked and can not be reset on the motherboard. Freaduino reset button to move the edge of the board, can easily click to whenever.

5 Wide input voltage. Arduino supports only 7-12V input, but Freaduino support 7-23V input.
