With this product you will be able to permanently install your Arduino application in no-time. Whether you use it for automation projects, data loggers or an interactive art installation, Industruino offers you ruggedness, plenty of features and low cost. 

Industruino PROTO offers a large prototyping area to add your own circuitry as well as the following features:

1. A 14 pin IDC expansion port to easily connect external modules such as the new Ethernet module or your own pcb/module hosting the same connector.

2. A 2A switching voltage regulator taking any input voltage between 7-28V and generating a stable 5V output for the MCU and your own components.

The prototyping area is generally used for two purposes:

1. To integrate a one-off Arduino based project into a fully enclosed solution. 

2. To prototype a design before making a custom Baseboard for mass production. 

Parts included are:

  1. D21G Topboard (Arduino Zero/MKR equivalent microcontroller)
  2. PROTO Baseboard
  3. DIN-rail enclosure with membrane button panel.
  4. Plug-in screw connectors

The controller comes fully pre-assembled and ATE tested.
