I bought 3 Pro Minis and an FTDI interface on eBay.
The FTDI interface is this one: http://www.ebay.com/itm/321498725216?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
I've connected them straight across since the pins seem to line up DTR - DTR RXD - TXD TX - RXI VCC - VCC CTS - GND GND - GND (it's the mini on the right)
When I plug it in, the power on LED on the Mini lights up and the pin 13 LED blinks.
When I try to upload a sketch, there's a LED on the FTDI card that blinks 3 times. The pin 13 LED on the Mini also blinks quickly. And then I get the dreaded "stk500_getsync(): not in sync: resp=0x00" message.
I've made sure there's a bootloader on the Mini by uploading it using an Uno as a programmer.
I've set the type of Arduino as "Arduino Pro or Pro Mini (5V, 16 MHz) w/ ATmega328" since that matches the eBay description.
I've also tried moving the jumper on the FTDI card between 3.3 and 5V with no success.
I've also tried connecting RX and TX on the FTDI card and making sure that any characters set were echoed back.
I'm kind of stumped and any help will be appreciated.
