Introduction
Types
Arduino Mega is an ATmega2560 core microcontroller development board. Itself has 54 digital input/output terminals (14 PWM outputs), 16 simulation inputs, 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 writers. Supply part of the optional USB power, or external power using a AC-to-DC adapter and battery.
Rapid growth due to open original code, as well as the concept of using Java (cross-platform) C language development environment for Arduino module. The Arduino can easily use the Arduino language with Flash or Processing ... software communication, to make multimedia interactive works. Arduino development IDE interface is based on open-source principles, allows you to download for use in projects.
Power supply design
There are two options for the power supply system of the Arduino Mega. USB direct power supply or external power supply. The 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 not stable; If the voltage is greater than 12V, the regulator device may possibly overheat and damage the Arduino MEGA. It is therefore recommended that for the operating supply of 6.5 ~ 12V, the recommended power supply is 7.5V or 9V.
The development board have been rigorously tested at the factory.

Getting started with Arduino products
It has four digits and a decimal point on each digit, designed for numeric output, so you can use it to add a clock, timer or counter into your next project.
These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.
This is an ultra bright RED colour.

UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)
UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!
Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V from your Batteries to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.
Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit!
Features
- Designed with an advanced switch mode DC-DC regulator IC.
- Battery polarity reversal protection.
- A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
- The working status is shown by an indicator (LED), which lights when the output is in normal range.
- Output Voltage: 5V@3A or 6V@3A (Changeable with an output-voltage select jumper)
- Continuous output current: 3 Amps
- Maximum output current: 5 Amps
- Input: 5.5V - 26V (2 - 6 cells lithium battery pack or 5 - 18 cells NiMH /NiCd battery)
- Size: 43mm*17mm*7mm (L*W*H)
