RS-232 input to HID output

Projects General Guidance

I'm wondering about the viability of this project. I would like to take a CCTV keyboard similar to this one:

...and use it as a combined keyboard & joystick PC input. (I am not concerned with the LCD function.)

The output of the keyboard is RS-232. I will need to capture these events (digital & analogue) and send them as HID inputs. I think the Leonardo will be a good candidate for this - or is that overkill?

Any general thoughts?

The Leonardo or the Micro would be a good choice.

Did you think about the circuitry you need? The Arduino isn't able to handle RS-232 input directly, you need a driver for that (p.e. MAX232). Do you know the protocol the device sends if there is any action on the keyboard/joystick?
