A second edge connector connected to the expansion slot is arranged on a top edge of the first circuit board and includes second power pins connected to the first power pins, second ground pins, and four first signal pins connected to the control chip. A third edge connector engaged in the expansion slot is arranged on a bottom edge of the second circuit board and includes third power pins and four second signal pins connected to the second storage chips, and third ground pins.
Abstract:
A serial advanced technology attachment dual in-line memory module device includes a power circuit, a storage chip, a control chip connected to the storage chip, and a detecting chip storing a preset voltage. The detecting chip includes a detecting pin connected to a power circuit through a first resistor and grounded through a second resistor, a ground pin grounded, a voltage pin connected to the power circuit, the control chip, and the storage chip, and an output pin connected to the storage chip. The detecting chip compares an output voltage of the power circuit detected by the detecting pin with the preset voltage, to output a control signal through the output pin to the control chip in response to the detected voltage being less than the preset voltage, to signal the control chip to control the storage chip to store data.
Abstract:
An electronic device with firmware recovery function includes a connecting port to connect the electronic device to an external device and a BMC. The BMC includes a firmware memory storing firmware data of the BMC and a microprocessor. The microprocessor determines whether the BMC is able to execute the firmware data in the firmware memory, and determines whether a download command for downloading firmware data is received from the external device when the BMC is not able to execute the firmware data in the firmware memory. The microprocessor further reads the firmware data from the external device into a memory space of the microprocessor upon receiving the download command, and recovers the firmware data in the firmware memory by writing the firmware data from the memory space of the microprocessor into the firmware memory. A related method is also provided.
Abstract:
A debug card includes a connector, a driving circuit, a switching circuit, and a testing circuit. The connector is connected to an expansion slot of a motherboard. The switching circuit is connected between the connector and the testing circuit to select data channels between the connector and the testing circuit through a low level signal or a high level signal received by a ground pin of the connector. The driving circuit is connected to the connector, the switching circuit, and the testing circuit, to provide voltages to the switching circuit and the testing circuit through the connector and the expansion slot.
Abstract:
A heat dissipation apparatus is used for accelerating heat dissipation of a memory card mounted to a circuit board. The heat dissipation apparatus includes a mounting bracket supported on the circuit board and a fan mounted to the mounting bracket. The mounting bracket includes to a mounting plate arranged over the memory card, and a plurality of legs extending down from the mounting plate to be fixed to the circuit board. The fan is attached to the mounting plate to align with the memory card.

Abstract:
A keyboard to control an electronic product includes an input unit, a code switching unit, a decoding unit, and a wireless output unit. The input unit receives a manipulation instruction and sends an electrical signal corresponding to the manipulation instruction to the decoding unit. The code switching unit receives a decoding instruction and sends an electrical signal corresponding to the decoding instruction to the decoding unit. The decoding unit decodes the manipulation instruction to a command recognizable by the electronic product according to the decoding instruction. The wireless output unit is wirelessly connected to the electronic product, thereby transmitting the command to the electronic product.
