Features
- ATmega 2560 @ 16MHz
- Selectable 5V/3.3V operation
- 70 Digital IO
- 16 Analog inputs
- 14 PWM outputs
- 4 Hardware serial ports (UART)
- Compatible with most Arduino Duemilanove and Diecimila Shields Small form factor, 30% smaller than Arduino Mega
- Easy to program, no additional hardware is required to load firmware - just plug to a USB port and you're good to go.
- ICSP Header
- Can be powered through a battery or through a AC to DC adaptor
- Label [5] The Seeeduino Mega uses a 4 Position mini-Type B Jack while the rest of the Arduino family uses standard 4 Position Type B Jack. The Arduino uses circular Power Jack.
- Label[9] The Seeeduino Mega uses a 2 Pin JST connector for the power supply while the rest of the Arduino family uses coaxial power plugs.
- Label[3] For the Reset button the Seeeduino Mega uses a an edge mounted push button while other Arduino based platforms uses a four legged tack switch .
- Yellow Labels are indicator LEDs.
- Blue Labels are mode selector and reset switches.
- Brown Labels are items that are common to the Arduino family; this makes the Seeeduino Mega compatible with most Arduino shields.
- Red Labels are the things that add the MEGA in the Seeeduino, the set includes additional ADC input pins and a bunch of bidirectional IO pins.

Great wiring harness for light installations.
Size: 16AWG Wiring Harness-2 Leads, Size: 16AWG Wiring Harness-2 Leads
This is a great wiring harness for LED lights. These come in one or two leads application. All that means is that they come ready for one or two lights, depending on your installation. The plug in connectors for each light comes with the set so that is a plus. I’ve attached a picture of the plug/connector for the lights so you can take a look at them. Although the relay is an “overkill” for low wattage LEDs, it’s OK to have it just in case you decide to change your lights for larger ones or halogens, in the future. In my case I will be using this harness in my motorcycle. It is very long for my need, which is great for cars, but too long for motorcycles since you have to remember that room/space is scarce in motorcycles. I ended up cutting the wires to my desired length and using heat shrink butt connectors and “glued” heat shrink covers for waterproofing the connection points. All in all these are great quality and I am very happy with them.

Wire length between the two connectors is short for a full-size pickup
Size: 16AWG Wiring Harness-2 Leads
I used the harness to wire ditch lights on opposite sides of a full-size pickup (F150). The wire between the 2 2-pin connectors was about 18 inches too short. Fortunately, splicing the wires from the (Nilight) ditch lights and the included pigtails gave barely enough length to reach the connectors. The connectors are buried inside the trim channel for the cowl; I'd have preferred they were exposed on each side to allow for easy swapping of the lights, but I can live with it. There is more than enough wire from the first connector to the relay for my all-under-hood installation, but I didn't think to measure if it would reach into the truck bed. The harness is of good quality and is a very good value. It would be a 5-star if it weren't for that little length issue.

great value
Size: 16AWG Wiring Harness-2 Leads
very affordable light install kit. worth the price just in the wiring connectors. I used this with my Nilight front bumper kit. i bypassed the button and wired high beam (+) to the yellow small wire. I did this so when the highbeams come on the light bar comes on. because with the stock arragement of this harness, the button continously draws power for the indicator LED
