@Frederic-Baumann Interesting... My theory is that when you plugged in the home-made PCB connector it initiated a factory restore (by droving a logical high voltage on GPIO11 for ten seconds or more). Were any of the other settings reverted to their defaults?
And to clarify if I understand your findings correctly:
Driving 3.3V to a GPIO before boot allows the Omega to boot successfully
Driving 5V to a GPIO before boot stops the boot sequence?
Hi @Rudy-Trujillo. With sensors you should go for digital sensors that can communicate with the Omega either through I2C or SPI (currently the Omega does not come with an ADC). If you want to use analog sensors, you can also use the Arduino Dock to relay the information back and forth between the Omega and the sensors.
