@Gayan-Priyanatha said in Power the Omega without board.:
Incorporating a power source regulator to Omega in design stage would have made the module much more independent from power intakes if we had an on-board regulator. Think of a very small IOT device using Omega2 without much PCB around it, an internal regulator module have made the module much more robust.
I understand what you mean, it would be useful for plug n' play and having the less components possible.
I think the creator wanted to make the module as generic as possible. Depending on what your are trying to interface to, you would probably have to add different power supply to a custom dock. For example, I have a project where I have 6x 24V solenoid valves that consumes 75mA each and a large NEMA23 stepper motor that I supply 5V to.
On the Arduino Pro Mini, the max voltage is 12V supply and the regulator can supply 150mA. What you do if you have a 24V power source? What you do if you need more than 150mA on the 5V (driving a stepper or relay)?
The less components you have, the more freedom you have to design what you want and choose your own parts. Personally the only thing that interest me is to have a CPU running Linux with RAM, Flash and WiFi. This is not something that can be done easily by an hobbyist on a 2 layer PCB. The others components such as power supplies/sensors/actuators are easy to integrate after that.
