Hallo,
I bought a sensor on your website and connected it according to the instructions.
I also passed the arduino nano and installed up-to-date libraries and examples, but arduino does not want to connect to AS7265.
the jumpers on the back and front sides are open.
I also tried to check it via uart, but it also does not respond to commands (I closed the jumper)
Please help to solve the problem.
i attached some images connections.
The blue and yellow wires go to SDA and SCL (it looks like they are mis-wired currently)…also if you are using i2c remove the solder from JP2 https://learn.sparkfun.com/tutorials/sp … okup-guide
If it still not doesn’t show up on i2cDetect you can cut the traces for the i2c pull-up resistors (there’s already a lot of resistance in the setup because of the multiple wire junctions)
HI,
i tried to cut the traces for the i2c but it not helped me.(checked with tester they are l2c open jp2 open too)
i tried 3 different arduino and got a same problem.

One of the chips on this board is a 3.3 volt chip and it looks like you’re powering it with 5 volts.
That might have fried the chip and that would cause the board to not work anymore. 
I used boards with a voltage of 3.3v just before connecting, I measured the voltage with a tester and there was 3.3v

I have also had issues. I started with the qwiic connectors, and that didn’t work. I was using Nate’s library, and tried multiple codes. The code would hit the lines that checked if the sensor was active, and freeze:
if (sensor.begin() == false)
{
Serial.println(“Sensor does not appear to be connected. Please check wiring. Freezing…”);
while (1);
}
I then commented out the while(); (and added a small delay) just to force it to move on and show me what data it would take. I would then get zeroes for the data approx. 10 out of 11 times. But that one time, it would work (example below). I could move my hand across the sensor and it responded; it also would respond to various colors of light from my phone (i.e. the appropriate values would increase or decrease). Once it did work, it would continue working; the values would not spontaneously return to zeroes.
This <10% working-time happened with both re-uploading as well as simply hitting the UNO reset button. I then soldering in headers and tried the I2C there, and got the same result. I have only used 3.3V, never 5V. I have removed and reinstalled the library.
Any help would be appreciated.

I found a workaround. In the void setup(){…} I put in a loop that checked to see if the sensor was responding:
if (sensor.begin() == false){ delay(500); }
else{ break;}
It would respond after anywhere from one to 20+ inquiries. However, once it did respond, it worked fine in the main void loop(){…} of the code. I guess it just needed a little attention to feel needed, and then it was happy to do its work. 
We are also facing same issues as posted by " pointsplitter". We have also posted one blog “SPARKFUN TRIAD (AS7265X) CONNECTIVITY ISSUES”.
We have posted some images and a video link for reference.
