USB Serial Adapter

I recently purchased you USB to serial adapter. What do I need in order to connect it to a microcontroller that talks via ttl? Do I need to use a chip like a MAX232? What is the serial output of your adapter?

Never mind. I figured it out. Thanks anyway.

Its great JK that u figured it out. Please tell me too…I am also going to purchase one.

The Pololu USB-to-serial adapter outputs 3.3V serial signals, and can accept signals at TTL levels (0V-5V) so you can connect it directly to a microcontroller running at 3.3V or 5V (or thereabouts).

It’s like having a USB to RS-232 virtual serial port plus a MAX232-style inverter/level shifter in one little board. Actually it’s better than that, since all of the handshaking lines are also brought out at TTL-safe levels. You also have access to the 5V USB bus voltage and 3.3V regulated voltage from the CP2102 level shifter chip, so you can even USB-power some low-current peripherals.
