  • I use this to send sketches to a prototype that uses a “bare” ATmega328 chip (https://www.sparkfun.com/products/10524) on a breadboard. To program the chip I hooked up the FTDI DTR pin to the RST pin via a .iuF capacitor, the FTDI RX pin to the TX pin and the FTDI TX pin to the RX pin on the ATmega328 chip. I didn’t use the 3.3v pin. I used http://www.yuriystoys.com/2012/02/arduino-on-beadboard-uploading-your.html as the starting reference because I couldn’t find clear instructions on SparkFun. I use the Arduino IDE to load the sketch and can monitor serial traffic just as if I were hooked up to an Arduino.

No public wish lists :(
