CY3269N - Low Battery Functionality

Question: What should I do if the HBLED on CY3269N flickers and stays off even though the board seems to be powered on (D3 – Red LED is ON)?




This will happen if the battery supplying power to the CY3269N board is fully depleted and is unable to source current for the HBLED. To work around this problem, replace the battery with a compatible one.
