This board is a really simple breakout for the Arduino Nano, designed with two principles in mind:

• Flexibility of setup
• Ease of installation and maintenance

The board is suitable for permanent or semi-permanent installations such as art/architecture projects, escape rooms, arcade cabinets, tool/machine control, etc...

Connections

Nano

Each Nano pin* is directly bought out to a 3.81mm pitch set of pads. These are intended for terminal blocks, but you could also just solder straight to the pad if you wished.

• Note: the 3v3 pin is not connected to the Nano. 3v3 is supplied from an onboard regulator.

Relays

Two relays are provided, connected to pins D2 and D3. COM, NC and NO connections are brought out to a 3.81mm terminal block header.

High Power MOSFET

An FDT457N MOSFET is provided on D4, providing a high-power high-speed open-drain switch. The drain is brought out to a 3.81mm terminal block header, along with 12V and 5V power.

Neopixels

The D5 output is connected to a 2.54mm header via a 330R resistor. Along with a 5V and GND connection, this provides a connection for neopixel strings (or just a normal LED, or anything else you might want to connect here!)

Power

The board is powered from a 12V supply. A DC/DC module provides 5V power up to 1A. A linear regulator provides 3v3 power up to 500mA.

The USB can be connected safely at the same time as the 12V supply without causing damage.

Options

Please select if you would like an Arduino shipped with the board, and if you would like terminal blocks fitting.
