Arduino MKR Cap Rail Mount

The new Arduino MKR series sets up a standard about form factor, function and performance for Arduino boards in the future. These new boards comes in a compact shape, with a powerful 32 bit Cortex M0 micocontroller Atmel SAM D21 and a charger function for LiPo accumulators. Furthermore Arduino offers in this series different types of MKR modules for different IoT wireless technologies. Besides the base model Arduino MKR Zero some further types with WiFi, WAN or GSM support are available.

I want to show you in this instructable - how to mount any board of the Arduino MKR series in a cabinet. This can be very useful for many professional applications like door access systems, smarthomes etc.

Materials:

• Arduino MKR board of your choice
• Arduibox MKR enclosure kit
• additional electronic parts of your choice
• thin solder wire

Tools:

• soldering iron with small tipside
• cutting pliers
• needle nose pliers
• medium cross slot screw driver

Find the terminal blocks, they're grey or blue and come in 2-pin and 3-pin shapes. We'll need to slide two 3-pin blocks together.

We've to put the blocks into the proto plate. Make sure you place them so that the openends are facing out as shown

bend the pins of the diode D2. Place the diode onto the pcb and solder the pins.

Sometimes it is hard to find header with 14 pins. You can use longer female headers a cut them to 14 pins....

Plug both female headers onto the male headers of the Arduino MKR board

beside the blue terminal block is a soldering jumper. You have to solder a bridge on this jumper if you want to connect later a external 5V power supply

Please take care to mount the holder from the inner channel to the outside!

It's possible to extend the basic kit with a voltage regulator (input voltage 9...35V; output voltage 5V)
