Rifqi - re-read my original post
. I said "To order one just search for "USB 2.0 to UART TTL 6PIN Module Serial Converter CP2102" on eBay
I said that they are made by www.betemcu.cn
but did not say to buy them there.Also
- be aware that these boards do not use the standard FTDI pinout
. Therefore, they are used to communicate with an Arduino but do not
have the Automatic (Software) Reset used for sketch loading. Some people modify
this board to provide the Automatic (Software) Reset, but you need to be somewhat hardware savvy to do this modification unless you purchase one of the CP2102 board versions that have the DTR brought out to an edge pin. Otherwise, more daunting surface mounted pin surgery is required. The easiest thing to do is to simply use this el-cheapo board for communications, not programming.
