Arduino Nano Breakout card

This card breaks out a Arduino Nano (not supplied with NANO-BKOUT card) into GVS (Ground-Voltage-Signal) headers for easy connection to external sensors.



  • Arduino Nano (not included with breakout card)
    • Inexpensive ($6-$7 US, $2.50 China), multiple sourced part
    • 5V, 16 MHz
    • Installs onto female header/removable
    • DC regulator
    • Microprocessor ATMega328 Comparable with Arduino UNO
    • Mini USB connector
    • Reset switch
  • DC Power Jack
  • GVS connections for most digital/analog signals
    • Ground and power connections for each digital lines simplify power distribution to external functions such as sensors
  • Additional analog input signals (over the Arduino UNO)
  • ICSP (In-Circuit System Programmer) header
  • I2C header
  • Aref voltage selection header
  • Direct connection to MyMenu card
    • I2C Interface
    • D6 connection for interrupt line
    • Located in mirrored location on both boards to allow the MyMenu to mount to the rear
  • 49x49mm form factor
  • (4) 4-40 mounting holes for installation into enclosures
  • Rounded corners to allow card to be installed into enclosure corners

Connectors - Rev X1


ISP Connector

  1. D12
  2. +5V
  3. D13
  4. D11
  5. RST*
  6. GND

(H18) AREF Select Jumper

  • 1-2 = External AREF (via shared power pins)
  • 2-3 = Use 5V as AREF = Factory position





Board Test


  • UUT
    • AREF Jumper installed from pin 2 to 5V Legend
  • Arduino NANO
  • POWER-49MM card
  • 2x LED-TEST-2 cards
  • Cable Set
  • USB or external DC power


  • The cable wires the LEDs to the UUT pins.
  • Pins A6 and A7 are untested since they are analog inputs only.

Test Station Cable Marking and installation locations are:

UUT Cable Marking and installation locations are:

  • D3 - Goes to UUT D3 (and D2) location
  • D5 - Goes to UUT D5 (and D4) location
  • D5 - Goes to UUT D5 (and D4) location
  • I2C - Goes to UUT I2C location
  • D8 - Goes to UUT D8 (and D7) location
  • D9 - Goes to UUT D9 location
  • D10 - Goes to UUT D10 location
  • SER - Goes to Serial location
  • ISP - Goes to UUT ISP location
  • A0 - Goes to UUT A0 (and A1) location
  • A2 - Goes to UUT A2 (and A3) location

Board Revs

Rev X2

  • Same netlist as X1
  • Moved I2C connector under the Nano to avoid interference with [MyMenu] connection

Rev X1

  • Tough to solder in the I2C connector when used with MyMenu card
