Hi Mathias, I'm assuming you're using a coin cell for back up, so wondering if one of the diodes shouldn't be in series with the battery, with both cathodes to V_BCKP? Nigel GM8PZR
I've updated the repository on github with the latest design files. The breakout board is now final as far as I'm concerned. I managed to implement all the requested features, this includes the backup battery and also the buffered PPS output with SMA footprint. Next step on my side will be to order a small batch of PCBs. There's not much on them and I guess I will end up with around 25? for 5 boards fully assembled, shipping not included. I eventually removed the I2C pull-ups again, thanks to Patrick Tudor for the hint. The footprints are still there, I only removed them from the BOM. Schematic and a screenshot of the top and bottom sides attached.
