Update

Hey folks, hope all is well out there. Here are the bits:

Weight sensor PCBs:

I discovered a couple of design issues with the right side PCB. Functionally, it all works but I sent a revision to the fab house to resolve the following issues:

  • Spacing for the HX711 signal amp pins are 2.54 mm too wide, one standard row off. I had to do some gross soldering to be able to test because of this.

  • Pins for the RFID reader are in a bad spot. With a minor layout adjustment we can remove the JST cable and replace with a 4 pin header.

Updated design went to the fab house late Wednesday night and is currently sitting at LaGuardia as of yesterday. Should have them in my hands tomorrow (Monday).

HX711 signal amp is mounted to the PCB underneath the RFID reader.

Other bits:

Nothing else to report just yet. Pin confirmation work has morphed into sensor service testing, so full brew testing is on hold for another day or two.

I will push another update out on Tuesday night. I will have most of the sensor work wrapped by then, as well as some more shipping details.

Thanks!
