PCI-E laptop test PCIE two digit diagnostic card, computer motherboard fault detection card

[Product Introduction]
1) Upgrade from one capacitor in VIP to two capacitors for more stable power supply.
2) Upgrading from VIP green light digital tubes to high brightness red light digital tubes makes it easier to observe.
3) Thoroughly solve the occasional digital garbled display phenomenon in the three in one VIP.
4) Compatibility.
The Taiwanese version of the Little Red Card inherits its consistent and rigorous design style. Using a red circuit board, a mini red high brightness digital tube, and using two large capacitors and several small capacitors on a small circuit board. Truly achieve small yet refined.
The main chip of the Taiwan version of the Little Red Card uses a Taiwan specific integrated circuit with 100 pins on all four sides, and its chip core is fully compatible with the core of the Little Green Card.
The Taiwan version of the Little Red Card is manufactured by a well-known Taiwanese OEM in Shenzhen, mainland China (due to confidentiality requirements, it is currently not disclosed which company it belongs to). Exquisite workmanship and attention to detail. Faced with numerous miscellaneous and pirated laptop diagnostic cards in China, the Taiwanese version of the Mini Red Card is known for its high cost-effectiveness and is the choice of laptop maintenance personnel.

Mini PCI-E interface of Xiaohongka
Mini PCI-E is a new interface that is gradually being used on laptop motherboards. Compared to the Mini PCI interface, the Mini PCI-E interface takes up less space. This diagnostic card uses the following pins of the Mini PCI-E interface: PIN-8, PIN-10, PIN-12, PIN-14, PIN-16, PIN-17, PIN-19。 Currently, not all laptop motherboards have this interface as not all laptops should have a standard pin definition. After testing, recent laptop motherboards such as Lenovo, HP, Fujitsu, Toshiba, Shenzhou, Acer, Yingyeda, and Guangda have been able to use this interface. For laptop motherboards that do not have this interface, it will not function properly. The following are the test results of some users for reference only.
HP: V6000 series, including CT6 and other models; V9000 series, including AT8, AT9 and other models
Lenovo: CW3, CW4, LE4, LE5 and other models
Shenzhou: 310320 and other models
Purple light: SYMPHONY6.0, 7.0 and other models
Acer: Most models
Fujitsu: PROTLAND10 and other models
Yingyeda: Most of the models produced by Toshiba and HP, and most of the models produced by Guangda
...
With the popularization and promotion of Mini PCIe diagnostic cards, more and more laptop manufacturers will start using this interface.
Reminder again: Not all Mini PCIe ports on laptop motherboards can run codes.
Mini PCI interface of Little Red Card
Mini PCI is an interface commonly used by older laptop motherboards, and its functional type is similar to the PCI bus. The MiniPCI bus has a total of 124 pins, and this diagnostic card achieves the required functions by using 101 of these pins. This diagnostic card can work on laptop motherboards of all Mini PCI slots.
Little Red Card LPC Interface
L
PC is a commonly used interface on motherboards. The definition of this interface on the diagnostic card is: PIN1 LFRAME # from left to right, in sequence, PIN2-LAD3, PIN3-LAD2, PIN4-LAD1, PIN5-LAD0, PIN6-GND,PIN7-LRESET#, PIN8-LCLK, PIN9-3.3V。 The use of this interface requires the use of flying wires. Most of Lenovo's ThinkPad series laptops are protected on the motherboard
The flight line interface has been left.
For the IBM X60 laptop motherboard, the LPC interface has been reserved on slot U39. Its definition is: A2->LRESET #, A3->LFRAME#, A5->LCLK, A9->LAD3, A10->LAD2, A11->LAD1, A12->LAD0
For the IBM T6 R6 motherboard, the LPC interface has been retained on pin J26. Its definition is: A1->LCLK, A3->LFRAME#, B2->LRESET#, B7->LAD3, A7->LAD2,B6->LAD1, A6->LAD0
For laptop motherboards that do not retain the fly wire interface, users need to connect the fly wire to the chip pins used on the motherboard. Below are some common chip flying methods, such as PC97551, PC87541, PC87591, H8S/2149, W83L950D, TCPA, etc
