An allegedly faulty USB 2.0 to UART TTL 6PIN Connector Module Serial Converter CP2102 is being sold on EBay http://www.ebay.nl/itm/110760144325
The TXD and RXD pins are wrongly labelled. Thanks to alco for finding this, more details are here.
I bought a simular item from the uk on Ebay that I couldent get to work but the guy came back to me saying to connect a switch for reset then when up loading hold reset until loading appears on the screen. That works fine but here it seems as though RX and TX are the wrong way around.
yeah I also connected the reset from the nanodeRF (emonbase) to the RST pins from the programmer, that works like an manual reset if you hold it exactlong enough after pushing the upload buton on arduinoIDE.. ..but it's not so handy like the use of the DTR witch auto-reset your arduinoboard.
for the record..this is the photo that explains it:).
Yes, I have bought three from Mr Chinaman not the same as that one above, they have TX & RX the wrong way around; but it's no problem as they seem to work ok when connected.
Yes, but it is a serious problem if you don't know that the terminations are wrongly described! Ask Alco.
Well on mine Robert its the RX and TX thats the wrong way as its only five pin. You soon find out when you don't read anything on the serial data screen and you can't upload.
