Proto-Screwshield (Wingshield) R3 Kit for Arduino Shipping:2-4 Weeks Built-in web service for easy

Built-in web service for easy monitoring and radar setup

some resistors

There is a built-in temperature sensor for air pressure compensation

The switch and control inputs control the state of a latching circuit that in turn controls a pair of power MOSFETs through which the main current flows

you can treat it just like a microcontroller+WiFi board

Proto-Screwshield (Wingshield) R3 Kit for Arduino Shipping:2-4 Weeks Built-in web service for easyThe next generation Proto ScrewShield is a dual purpose prototyping shield. Not only does it have a large 0. 1" grid prototyping area but it also extends the Arduino pins to sturdy, secure, and dependable screw terminal blocks. You even get a few bonus terminals for extra GND and four 'free' terminals for whatever connections you wish ! As of June 23, 2014 we now have an R3 update to this design we now have a stacking header for the ICSP 2x3 pins and
