This option is not factory configuration
R6 and R7 can be used to shift the address of the 64 bit version of the card from 0x20-0x23 up to 0x24-0x27
- Clip out R7 jumper to shift address up (not typical use)

 == R6/R7 Option ==
+* This option is not factory configuration
 * R6 and R7 can be used to shift the address of the 64 bit version of the card from 0x20-0x23 up to 0x24-0x27
-* R6 pulls up A2 to Vcc (only if R7 is not installed) (64-bits only)
+** Clip out R7 jumper to shift address up (not typical use)
-* R7 provide pull-up or pull-down for I2C address A2 line
-* R7 is 0 ohm jumper
-* R6 is 10K resistor
-=== DIGIO-128 - 128-bit option ===
-* Leave R6 open (no resistor)
-* Install jumper wire into R7
-=== DIGIO-64 - 64-bit option ===
-* Typical Operation - for I2C address = 0x20-0x23 leave R6 open, install jumper wire into R7
-* For I2C address = 0x24-0x27 leave R7 open, install 10K resistor in R6
-* I2C chips get installed into top 4 locations
