## Errata
Due to component shortage 2022 only the 16kB flash version was sourcable (32kB not availible). It does not have any real implications as the FW only takes 6k + 2k bootloader. Crazyradio PA's manufactured with date code after 2022-06 will have the 16kB version. This can also be idetified on the chip marking. Locate the biggest chip that says NRF in the top. The 32kB version will say 24LU1P on the second row and the 16kB LU1P16.
