The module's flash bus is connected to the pin header JP13 through 0-Ohm resistors R140 ~ R145. If the flash frequency needs to operate at 80 MHz, to improve integrity of the bus signals, it is recommended to desolder resistors R140 ~ R145. At this point, the module's flash bus is disconnected with the pin header JP13. .. important::
