pairing arduino and a propeller

Has anyone paired an arduino uno board with a propeller. I am thinking of using an arduino uno board to create "chameleon" type board. Can the arduino board power a propeller dip and serial memory chip?

    I have paired a Arduino Pro Mini 3.3V with the Propeller so I didn't have to worry about voltage translation since the Uno uses 5V logic. I used a PPDB with it and had no trouble powering the Pro Mini with it.

    I tried using serial communication between them but had issues since I was using the Pro Mini's hardware Serial port which is also used to program it.

    You mentioned the Chameleon AVR. The manual to it could give you a few ideas which can be downloaded at ic0nstrux.com/chameleon-avr-8-bit-system.

    BTW I have the Chameleon PIC which is a fun board to use.

    I use an Adafruit Circuit Playground with a propeller which is a 3.3 V device and use the Serial1 Port connected to four port serial plus on the prop.

    Thanks for the replies...I guess my overall question is..can the arduino board's 3.3V power supply provide enough mA to power both the arduino board and a propeller? The arduino board list "dc current for 3.3V pin 50mA". That seems very low. Plus I have noticed other LCD projects (with backlights) powered from the board that have to be using more than 50mA.
