So, i have an AS7265X Spectrometer and as I hooked it with my Arduino MEGA, i noticed that the power LED that is in the board is dim. It seems like the sensor isn’t getting enough power? while i tried to plugged it to the 5V Pin of the Arduino MEGA , and the Power LED and Stat LED is working fine. What could be the issue?
The sensor power and I/O is 3.3V ONLY, so you need bidirectional logic level shifters to connect it to a 5V Mega. If you applied 5V power to the sensor, you probably have damaged it.
