Good day,

I have recently purchased the ProtoCentral AFE4490 Breakout Board Kit . I have connected and tested the kit with my Arduino Uno R3 and Nano R4, but the red light on the finger probe does not come on. I have tried all of the example code from ProtoCentral using their Arduino library, but still no red light. I have also tried 2 different finger probes, but the same issue. I have used a finger probe from the hospital and the one that the kit came with. The signal is also very noisy with random massive spikes upwards. Do I have a faulty board or is there an issue with the code?

Any help or suggestions are appreciated!

Thank You
