I just got the part tonight and started connecting it.Like the previous poster, I also found the silkscreen to be incorrect. This is a big annoyance. There are two AINP1 signals and two AINP2 signals labeled, but none labeled as AINN1 and AINN2.It would be very helpful if the seller could provide a simple schematic of the board. It is not obvious how the two capacitors are connected. I had to trace the copper to figure out that REFN is connected to ground on the board. This is not ideal for me, I would prefer to connect the reference voltage differently to maximize the available range for my sensor. It would also mean another pin along the edge.I also see they swapped PMDN and PWDN. Easy to correct, but helpful if it was correct.

TL;DR See image for PCB pinout typos. Perfect match replacement for HX711, not for beginners due to lack of online support and material.I've never seen typos on a PCB so I'm taking one star off for that because that's not helpful at all when trying to hookup your circuit. I could excuse PWDN being PDMN because it's the only pin close to that name but when you print AINP2 and AINP1 twice when one should be positive and the other negative, you have to follow the traces or get your multimeter out to figure out which pin is which. I've taken the liberty to include a picture with the actual pinouts labeled. And the two in the middle are for an external clock, they aren't labeled at all but I checked it with a multimeter and followed the traces.Aside from the typos, this module seems to work great so far, I was previously using an HX711 and wanted to see if this one offered any improvement since it has a temperature sensor which can be incorporated to adjust for drift due to ambient temperature changes. I haven't gotten that far into my research but so far the module performs with the same accuracy and results as the HX711.If you are just getting started with MCU projects I would definitely recommend the HX711 as there is WAY more documentation and user experiences online. I had to work solely out of the datasheet to get this one set up, there are hookup images online but most are from individuals asking for help so they are likely wired incorrectly. I posted an image of how I had mine hooked up (A+ and A- are what would normally go to A+ and A- on the HX711 and then E+ goes to 5V and E- to Gnd). I'd say comment if you have questions but I Amazon doesn't always notify of comments on reviews.
