USB To TTL UART stick

[rmeldo]

Hi,

I have mislaid my USB to serial TTL stick so I need to buy a new one. I have been looking at something like this: http://www.ebay.co.uk/itm/182388994594 which is similat to what I had before.

What I would like though is something which has the voltage conversion (from 5 to 3v3) for the Tx and Rx pins as well, but I am struggling to find it.

Any recommendations?

Thanks
Riccardo

All CP2102 Based USB/TTL Modules have 3.3v Output level on the TX pin and are tolerant of 5V input on the RX Pin. And of course these levels will need to be inverted for Picaxe Programming.

Thanks very much for the advice.
