The FourBoard1.1 is an open-source hardware expansion for Arduino Nano.
It combines some of the most common circuitry used with Arduino
onto a single board allowing to move directly from programming to controlling electronics.

The FourBoard1.1 requires Gravitech's Arduino Nano http://www.gravitech.us/arna30wiatp.html
to be programmed then can be used with projects using simple input or power output larger than an LED.

There are 4 of each of these basic Arduino setups on board:
Arduino to Potentiometer Dial (A0,A1,A2,A3)(https://www.arduino.cc/en/tutorial/potentiometer)
Arduino to Power Transistor (D6,D9,D10,D11)(http://bildr.org/2012/03/rfp30n06le-arduino/)
Arduino to Button (D2,D5,D7,D8)(https://www.arduino.cc/en/tutorial/button)
FourBoard1.1 connects to components easily with its screw terminals.

(IRF540 http://www.infineon.com/dgdl/irf540n.pdf?fileId=5546d462533600a4015355e396cb199f)
on FourBoard1.1 are connected to Arduino PWM pins and configured as sinking outputs.
With appropriate power input, each channel is recommended to output up to
50W, 36V, or 3A continuous per MOSFET channel.
Multiple power channels may be combined in parallel for a single device.

2 digital pins (D3,D4) and 1 analog pin (A6) are also routed to the screw terminals,
for use with an external interrupt or software serial,
as well as USB/hardware serial pins(D0,D1) and I2C(A4,A5) for integrating with other systems.

FourBoard1.1 makes programming Arduino ready to use
without the need of wiring fundamental circuits needed in most projects.

FourBoard1.1 is available Assembled, without Arduino Nano
Also available as an Unassembled Kit
