Hi @Brian-Moreau, the Omega itself does not have an on-board ADC, so if you want to use it to read analog sensor data, you will need the Arduino Dock. It does have PWM output, and as @Kit Bishop pointed out, you can use fast-gpio to control the PWM output. More information about the fast-gpio library/command can be found here: https://onion.freshdesk.com/support/solutions/articles/6000069970-can-i-do-pwm-with-the-expansion-dock-.
