Based on the discussion in the topic below, we will be updating the MicroZed Errata document to include an incorrect value for R42 on Revisions B, C, and F01. Moving forward, new MicroZeds will be built with this change. Since this is not a PCB change, we expect that the new revision will be Fxx, where 'xx' represents the BOM version. We are waiting hear back from manufacturing to know what that 'xx' number will be, after which the Errata will be updated.
