  • Great product and I have used both the 434mhz and 915mhz with no issues. One thing that I would like to point out is that you can get the exact same module in whatever quantity you want, directly from the manufacturer for about $4 with no manufacture lead time and 4 day shipping.

  • I’m trying to use this opamp in conjunction with a simple 3-wire load sensor sourced from a bathroom scale. When I connect the opamp and load sensor to a common 5vDC supply and ground and measure the output voltage from the opamp, I’m reading a constant ~2.7v and it will only occasionally fluctuate with weight applied to the sensor. I’ve tried adjusting the onboard trimpot as well with no prevail. Any ideas on what the issue could be? I’ve tried two different opamps and load sensors as well with the same results. Any insight would be appreciated.

No public wish lists :(
