Adafruit FTDI Friend + Extras

Key Features:

• Genuine FTDI chips
• Extra-long headers that you can use to plug it into a breadboard
• 2 red & green LEDs already on the board that pulse when serial is sent or received
• Signal Levels are they are 5V compliant, and should work in most 3.3V and 5V signal systems

Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the FTDI Friend!

The FTDI Friend is a tweaked out FTDI FT232RL chip adapter. Sure, like the well-known FTDI cable, it can provide power to your project and there are 4 signal lines for sending data back and forth. But the Friend can do much more! For example, you can change the signal and power lines to be either 3.3V or 5V. Arduino-derivatives and XBees use the RTS line for programming but what if you need that DTR line? It's there for you.

By default, it's setup so that it matches Adafruit's FTDI cables. The 6th pin is RTS (as of Arduino IDE v18 this will work perfectly for uploading to 'inos), the power wire is +5V and the signal levels are 3.3V. You can even rearrange the wire order with a 6-pin extension cable (not included). In a pinch, you can use it to program AVRs (its a bit slow but works!)
