LED status indicators:
Steady Red LED lighting indicates that the rated output power reaches the standard,
The Red LED Not bright or flashing indicates that the power supply less than the rated output standards.
Please Note:
1.When the load tester is operating, it will cause high temperature because a huge amount of current flow through the winding
resistor. Please don't touch the winding resistor during the usage process or when you just finish your usage.
2.Due to winding resistor's particular features, there might be a little smoke or strange smell after you power up the USB load
tester for a certain time in your first usage. This is normal phenomenon and will disappear finally.

Mini Nano V3.0 ATmega328 board for Arduino IDE (Arduino-compatible) + USB Cable
It is a smallest, complete, and breadboard friendly. It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard +5V AREF jumper. Physically, it is missing power jack. The Nano is automatically sense and switch to the higher potential source of power so there is no need for the power select jumper. Nano's got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. It's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other). This new version 3.0 comes with ATMEGA328 which offer more programming and data memory space. It is two layers. That make it easier to hack and more affordable. You end up paying less with Nano than Mini and USB combined!

Mega2560 R3 ATMEGA16U2 + USB Cable for Robot Arduino UNO MEGA2560 R3 DCCduino
The Mega 2560 is an update to the Arduino Mega, which it replaces.
The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the ATmega16U2 programmed as a USB-to-serial converter.
Reversion 3 of the board has the following new features:
1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
Stronger RESET circuit.
Atmega 16U2 replace the 8U2.
