Getting the MKR2UNO Plus board out of the box
The MKR2UNO Plus comes in your hands as shown in the picture below.
The MKR2UNO Plus right out of the box
The MKR2UNO Plus consists of:
- 1x MKR2UNO Plus PCB with all SMD components
- 2x 14 way, 2.54mm pitch, headers
- 2x 8 way, stackable, 2.54mm pitch, headers
- 1x 6 way, stackable, 2.54mm pitch, header
- 1x 10 way, stackable, 2.54mm pitch, header
- 1x pushbutton
- 1x 2.5mm DC connector
Assembling the 14 way headers
First you have to solder the two 14 way headers as shown in the picture below.
Assembling the two 14 way headers
Assembling the reset pushbutton and the 2.5mm DC connector
Even if it is not mandatory, since the board works properly without these two items, you may choose to solder the reset pushbutton and the 2.5mm DC connector.
Or you can decide to add them later.

Assembling the stackable headers
Stackable headers can be soldered in two differt way: the “standard” way or the “long headers” way.
Assembling the stackable headers in the “standard” way
Assembling the stackable headers in the “long headers” way
To better understand why you should choose one way or the other, you have to consider the Arduino MKR board and the environment you are going to use in your project.
Arduino MKR boards come with pin stripes or stackable headers.
Arduino MKR1000 with pin stripes
Arduino MKR GSM 1400 and MKR Vidor 4000, both with stackable headers
The “standard” way allows the MKR2UNO Plus to fit both stackable headers and pin stripes boards.
The “long headers” way allows the MKR2UNO Plus to fit only pin stripes boards.
Unless you are going to use an Arduino MKR board with pin stripes AND your project needs a “long headers” layout, we suggest you to solder them in the “standard way” which allows the MKR2UNO Plus to fit any Arduino MKR board.
