 ## SPI-Flash Memory
 
-SPI-Flash memory can be replaced with an other type. Because the chip is defect, like #69 & #70 or you have an unmanaged-switch with a small flash size, and want to convert it to a managed-variant to run `RTLPlayground` software on it. Currently `RTLPlayground`-firmware expects `8 MBit / 2 MiB`.
