NANO-BKOUT

Arduino Nano Breakout card

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

Features

• Breakout card for the Arduino Nano
• NANO (not supplied) is:
  • 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
• NANO-BKOUT has
• 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

Board Test

Hardware

• 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

Cabling

• 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:

• L01 - Goes to LED-TEST-2 card #1 LEDS 1-4

• L09 - Goes to LED-TEST-2 card #1 LEDS 9-12
• L13 - Goes to LED-TEST-2 card #1 LEDS 13-16
• L17 - Goes to LED-TEST-2 card #2 LEDS 1-4
• G1 - Goes to POWER-49MM card on "-" pins
• G5 - Goes to POWER-49MM card on "-" pins

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

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
