Item Precautions
芯片型号 The specific model of the FPGA chip used by Tang Mega 138K isGW5AT-LV60PG484A

Please select the package model PBG484A in the IDE.
Static Electricity Please avoid static electricity hitting the PCBA; release the static electricity from your hands before touching the PCBA.
Tolerance Voltage When using GPIO pin headers for external communication, ensure that the IO voltage is 3.3V. Excessive voltage will permanently damage the PCBA.
FPC Socket When connecting the FPC soft cable, please ensure that the cable is completely and correctly inserted into the socket without any deviation.
PCIE Gold Finger When testing the PCIE gold finger, ensure that both the host and the board are in the off or unpowered state to avoid short-circuiting the gold finger due to displacement during the insertion process.
Plug and Unplug Please completely power off before plugging and unplugging.
Avoid Short Circuit Please avoid any liquid or metal touching the solder pads of the components on the PCBA during the power-on process, otherwise it may cause a short circuit and burn the PCBA.
