RS232... level shifter?
« on: October 17, 2008, 09:55:59 PM »
If I'm going to make a simple serial wire to talk to my pc port from one of the Axon UARTs... do i need to make a "level shifter"?

pc port

You mean a serial port?
You can buy a TTL to serial adaptor, or use RS232.

This is probably the cheapest/easiest:
