If you downloaded the Bill of Materials since May 1, I apologize as it was not the version I intended to upload and did not have current information for the Rev C.3 and C.4 boards - specifically regarding the IMU module and the RTC power supply. I have posted a new one with current info and updated links.
Also, a new version of the Caveatron firmware is available. The only change is for the Caveatron SV and fixes failed LRUDs and points when using the HEX mode LRF.
