Procedure to test RPI-Console-U card

GVSDuino wired to custom board

• Wire V5-1 header pin S (pin 3) to GVSDuino pin 3 (TX)
• Wire V5-2 header pin S (pin 3) to GVSDuino pin 4 (RX)
• Wire V5-1 header pin GND (pin 1) to Arduino GND pin
• Wire V5-1 header pin +5V (pin 2) to Arduino +5V power

Test Software

• Poll for receive character
• When character is received, echo back character
• Loop forever
• Code on GitHub

Test Procedure

• Test setup as above
• Test setup powered down
• Install UUT (RPI-Console card being tested)
• Install P1 jumper on UUT (power the test station from the RPI-CONSOLE)
• Connect USB cable from Test Computer (laptop) to UUT
• Boards should power up
• Look in Device manager to make sure COM port was added
• Run putty on Test Computer (laptop)
  • Select COM port in putty
  • 9600, n, 8, 1
  • No handshake* Select COM port in putty
• Hit reset on Arduino Shield or attached to GVSDuino
• Verify the message comes back

Rev X3 (vs X2)

• Moved "Power Pi from USB" connector to center of card
• Rev X2 (vs X1)
• Moved connector slightly closer to the edge
• Made USB connector PWB pads longer
• Adds ID resistor pads to USB pin
  • Not populated

Rev X1 Checkout

• Micro USB mounting holes fit well
• Connector could be slightly farther to the edge
• USB connector PWB pads were too short - trimmed pins to fit
• Ordered 3 more from OshPark new X2 rev
