MEGA 2560 R3 ATmega2560 MEGA2560 Development Board + 3.5 Inch TFT Color Display 320x480 Screen

Mega2560 Description:

This is compatible R3 Mega2560 ATmega2560-16TW (upgrade version) control board with USB cable
This is an ATmega2560 as core microcontroller development board itself has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery.
Rapid growth due to open the original code, as well as the concept of using Java (cross-platform) C language development environment for peripheral module. The main reason attracted Artist can quickly use the language with Flash or Processing ... software communication, to make multimedia interactive works. development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive works.

Power supply design:

There are two options for the power supply system of the Mega USB direct power supply or external power supply. The choice of power supply will be switched automatically. External supply AC-to-DC adapter or the battery can be selected on this control panel. Limit the voltage range of 6V - 12V, but if the voltage supplied is less than 6V, I / O port may not be supplied to a voltage of 5V, and therefore instability; If the voltage is greater than 12V, the regulator device may possibly overheating protection, are more likely to damage the MEGA. Therefore recommended operating supply 6.5 - 12V, the recommended power supply to 7.5V or 9V.
The development board have been rigorously tested each product at the factory before to burn a Blink small program, please get the goods energized inspection under the L lamp will be lit for 3 seconds and then off for 1 second, non-stop cycle to Detection of the board is good or bad.

Note:

The control and driving circuit of TFT modules is low voltage and  FRIDA micro-power CMOS circuit, can be easily damaged by static, static damage is an irreparable damage, and sometimes human have hundreds of volts of high voltage static electricity, therefore, in handling, assembling and use should be extremely careful to prevent static electricity:　
1. Using soldering iron or  power FRIDA tools must be well grounded and operation, make them without leakage;
2. Do not use hand to touch the leads, circuit boards and metal boxes;
3. Do not use a vacuum cleaner for cleaning, because it generates strong static electricity;
4. When the air is dry, can also generate static electricity, therefore, workshop humidity  shall be above RH60%;
5. If it is necessary to direct contact it , should enable the human body in the same potential with the modules? ,ormake  human body be well grounded;
6. Remove or back in the bags or move locations, also need to be careful to prevent static electricity. Don't replace or discard the original packing.
