J-Testr LVIO Breakout Card

About

The Low Voltage IO (LVIO) Breakout card is configured in to eight banks groups of 16 IO lines as below:

BANK0_F1_(0-15)   -              Bank0 00..15 IOs
BANK0_F2_(0-15)  -              Bank0 15..31 IOs
BANK1_F1_(0-15)    -              Bank1 00..15 IOs
BANK1_F2_(0-15)   -              Bank1 15..31 IOs
BANK2_F1_(0-15)   -              Bank2 00..15 IOs
BANK2_F2_(0-15)  -              Bank2 15..31 IOs
BANK3_F1_(0-15)   -              Bank3 00..15 IOs
BANK3_F2_(0-15)  -              Bank3 15..31 IOs


Each bank group is attached to two sperate Minitek 1.27mm 12Way shrouded Headers for ODDs and EVENs IO numbers. Each connector group have 3 groups and 1 legacy (obsolete JTAG IO Card) no connection.

Each connector is clearly marked with its bank group and if it contains ODDs or EVENs, as well as all connectors Pin 1 locations being clearly marked. This makes IO location very simple.

There is a pull-down resistor on each bank group IO_0 for convenience when testing input functions.
