content: Hi guys!In my Intelligent Sensors class I am going to use the Microstick for 5V PIC24 (http://www.microchip.com/Developmenttools/ProductDetails.aspx?PartNO=DM240013-2) and I need a USB to TTL adaptor.The Microstick uses the same pinout as the FTDI.Do you know of any USB to TTL adaptor that I can use that is relatively cheap?In my research I found this one:http://www.ebay.com/itm/PL2303TA-USB-TTL-to-RS232-Converter-Serial-Cable-module-for-win-8-XP-VISTA-7-8-1-/400708482567?hash=item5d4c163607:g:rrkAAOSwhOVXdyDibut I don't know if it works with 5V logic.Summing up, do you know of any USB to TTL adaptor with the same pinout as the FTDI that works with the Microstick for 5V and that costs not too much money?Best regards,Miguel

content: Avoid FTDI since they have a high probability to be faik and will not work on recent computerInstead opt for CP2102 that does not have this program and work flaw lesshttps://pt.aliexpress.com/item/CJMCU-CP2102-MICRO-USB-to-UART-TTL-Module-6Pin-Serial-Converter-UART-STC-Replace-FT232-NEW/32579477293.html?spm=2114.02010208.3.1.os0sd6&ws_ab_test=searchweb201556_0,searchweb201602_3_10057_10065_10056_10068_10037_10055_10054_10069_301_10059_10033_10058_10032_418_10073_10017_10070_10060_10061_10052_10062_10053_10050_10051,searchweb201603_2&btsid=c0c75ac0-c5f0-468f-987f-119db0122f25

content: That seems a good option, but it does not have the same pinout as the FTDI adaptors, the same as the Microstick.This one seems like a good option, but I can't find it in Europe at decent prices:https://www.pololu.com/product/1308

content: Thank you again.But that one has the same problem as the one you posted before. It does not have the FTDI cable pinout, so I can't plug it directly in the Microstick.I don't know if I am asking to much but what I wanted was an USB to TTL adapter with:FTDI pinout;5V tolerant;Good drivers;Cheap;

content: Yes, I know...But it would be much easier and cleaner if I could plug it directly.But thank you very much! The CP2104 seems like a very good option!
