I bought this diagnostic card from AliExpress but the instructions were not the best but there is a lot of information in the product page. I am merging the information I find here.

• TL631 Pro Universal Laptop And PC PCI PCI E Mini PCI E LPC Motherboard Diagnostic Analyzer Tester Debug Cards|Instrument Parts & Accessories| - AliExpress
  • Some examples of how users have used their debug cards
  • Eakins Store are good to deal with

Other Notes

• If a motherboard has a PCI slot and PCIE slots. there is a good change the debug headers are in the PCI socket, it will not be in both.
• only one of the PCIE/PCI sockets might support debug. This is useful to know.

Another description

• TL631 PRO uses the new 130-nanometer Actel ProASIC3 flash memory series chip with a new pure system.
• Gemini drive module: BGA type driver module, part design.

TL631 Pro interface description:

1. LPC1 shared high-speed channel = connect to the motherboard 2.0 small pin LPC interface, 2.0 module
   (Module expansion LPC3 interface can connect notebook MINI PCIE conversion card, A-DEBUG conversion card, ASUS notebook DEBUG-CON. EC-DEBUG).
2. PCI high-speed channel = support all PCI slots.
3. LPC2 shared high-speed channel = connect to the motherboard 2.54 large pin LPC interface, ASUS COM-DEBUG. ASRock UART1, MSI JDP, SuperMini SPl.
4. PCIE X1 high-speed channel = support Gigabyte without PCI motherboard (other brands do not support).
5. 3VSB power indicator, to detect whether the power is normal.
6. RST reset indicator, to detect whether the motherboard reset is normal (only when PCI or PCIE is inserted)
7. CPU indicator light, to detect whether the CPU module is normal.
8. DRAM memory indicator, to detect whether the memory module is normal.
9. VGA graphics indicator light, to detect whether the graphics card module is normal.
10. PCH south bridge indicator light, to detect whether the south bridge module is normal.
11. DP decimal point, CLK signal display.
12. DP decimal point, FRAME frame signal display.
13. threading hole

Identification of Components

1. LPC1 shared high-speed channel = connect to the motherboard 2.0 small pin LPC interface, 2.0 module
   (Module expansion LPC3 interface can connect notebook MINI PCIE conversion card, A-DEBUG conversion card, ASUS notebook DEBUG-CON. EC-DEBUG).
2. PCI high-speed channel = support all PCI slots.
3. LPC2 shared high-speed channel = connect to the motherboard 2.54 large pin LPC interface, ASUS COM-DEBUG. ASRock UART1, MSI JDP, Supermicro SPl.
4. PCIE X1 high-speed channel = support Gigabyte without PCI motherboard (other brands do not support).
5. 3VSB power indicator, to detect whether the power is normal.
6. RST reset indicator, to detect whether the motherboard reset is normal (only when PCI or PCIE is inserted)
7. CPU indicator light, to detect whether the CPU module is normal.
8. DRAM memory indicator, to detect whether the memory module is normal.
9. VGA graphics indicator light, to detect whether the graphics card module is normal.
10. PCH south bridge indicator light, to detect whether the south bridge module is normal.
11. DP decimal point, CLK signal display.
12. DP decimal point, FRAME frame signal display.
13. Threading hole
    • This is possibly to attach a cord to be able to pull the card out easier.

Number 4 is obviously RAM

Debugging Examples

I believe are examples of how the device should be plugged in.
