@ccs-hello said in Omega 2 boot problem: 2...3sm 470uF 6.3V low ESR capacitor I tried, didn't help I'll buy some other regulators, try them.

@Andrew-Moore You are very welcome! The Arduino Dock 2 contains a 6 channel, 10-bit analog to digital converter, meaning that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023.
